Bosch Dishwasher Repair Cost — 500, 800 & Benchmark Series | Northern Virginia

Quick answer

Bosch dishwasher repair in Northern Virginia typically costs $100–$480 depending on the fault and series. A drain pump (E24 error) runs $140–$260. A circulation pump runs $180–$320. The AquaStop supply hose assembly (complete, flood-sensor integrated) runs $120–$220. The EcoSilence Drive motor assembly (800 Series/Benchmark) runs $220–$400. The CrystalDry zeolite mineral module (800 Series/Benchmark) runs $150–$280. A control board runs $220–$380 on the 500 Series and $280–$480 on the 800 Series. Against a $900–$2,500 true replacement cost, most single repairs are clearly worth doing.

Bosch dishwashers — the 500 Series, 800 Series, and Benchmark — are among the most prevalent premium dishwashers in Northern Virginia kitchens, from McLean and Great Falls single-family homes to Bethesda and Arlington condos renovated between 2014 and 2024. When a Bosch 800 Series develops a fault — a drain error, a drying failure, a pump that surges — the first question is whether to repair or replace a dishwasher that costs $900 to $2,500 to replace installed. This guide gives part-by-part repair cost ranges for all three Bosch series, explains the Bosch-exclusive components — AquaStop hose assembly, EcoSilence Drive motor, CrystalDry zeolite module — that make some Bosch repairs different from a standard dishwasher service, and works through the repair-vs-replace math at each price point.

Why Bosch dishwasher repair costs more than a standard dishwasher

Bosch 500, 800, and Benchmark series dishwashers share three design features that add cost and specificity to service versus a standard residential dishwasher. (1) AquaStop 2-layer supply hose. Every Bosch dishwasher ships with a proprietary AquaStop supply hose — a 2-layer hose with a flood-detection sensor integrated into the connector housing at the appliance end. If the outer layer of the hose detects moisture (an internal leak), the sensor shuts off water supply before the flood reaches the floor. When the AquaStop hose assembly needs replacement — due to a kinked hose, a cracked connector, or a tripped flood sensor — the COMPLETE AquaStop hose with integrated sensor must be replaced as a unit. A standard aftermarket washing-machine supply hose fits the connection point but bypasses the flood-protection sensor, removing a safety feature Bosch built into the installation spec. OEM AquaStop hose assembly replacement is the correct repair. This is the Bosch supply-hose constraint: 0 nationally documented in non-Bosch-specialist repair guides. (2) EcoSilence Drive brushless motor (800 Series and Benchmark). Bosch 800 Series and Benchmark dishwashers use an EcoSilence Drive motor — a brushless DC motor with ceramic bearings that produces 42 dB (800 Series) or 40 dB (Benchmark) during the wash cycle. When EcoSilence Drive ceramic bearings wear — producing a low grinding or rumble during the wash phase — the motor assembly must be replaced as a unit. The ceramic bearings cannot be replaced independently (they are integrated into the motor housing under factory tolerances). A standard Bosch dishwasher motor without EcoSilence Drive certification produces audible operation inconsistent with 800 Series acoustics; OEM EcoSilence Drive motor assembly is required. (3) CrystalDry zeolite mineral module (800 Series and Benchmark). Bosch 800 Series and Benchmark dishwashers include a CrystalDry zeolite mineral container in the base of the dishwasher. The zeolite mineral absorbs moisture during the rinse cycle and releases stored heat during the drying phase — producing residual-moisture-free drying without a heated-air element. After 8–12 years of regular cycling, the zeolite mineral exhausts its absorption capacity and dishes emerge with residual moisture on plastics and glass. CrystalDry module replacement requires a Bosch OEM zeolite container — no aftermarket equivalent exists because the mineral grain size and container geometry are calibrated to Bosch's drying-cycle timing. NVA water note: Northern Virginia's municipal supply tests at 180–230 ppm (moderate-to-hard) in Fairfax County and McLean service areas. This hardness level accelerates mineral scale deposition on EcoSilence Drive ceramic bearings (through wash-water spray ingestion over years of cycling) and on the AquaSensor optical turbidity lens — the most common cause of extended-cycle faults on Bosch dishwashers in NVA that have not had a scale cleaning.

Bosch dishwasher repair costs — part by part

These are realistic installed cost ranges — part plus labor — for Northern Virginia Bosch 500, 800, and Benchmark dishwasher repairs in 2026. Diagnostic fee: $99–$149, credited toward repair. (1) Drain pump — the pump that evacuates water from the tub at the end of each rinse phase. Bosch drain pump failure typically presents as an E24 error code and standing water at cycle end; occasionally an E25 (drain blocked) code appears first when the impeller is partially obstructed. Drain pump replacement: $140–$260 parts and labor. (2) Circulation pump (wash pump) — the main pump that pressurizes water to the spray arms during the wash and rinse cycles. Circulation pump failure or bearing wear produces a grinding or surging sound during the wash phase, reduced spray pressure, or dishes that emerge wet with food residue. Bosch circulation pump replacement: $180–$320. (3) AquaStop supply hose assembly — the 2-layer flood-protection supply hose with integrated sensor. Replacement required when the hose body is kinked, a connector cracks, or the flood sensor trips and cannot be reset. OEM AquaStop assembly only — aftermarket hoses bypass the flood sensor. AquaStop assembly replacement: $120–$220. (4) Water inlet valve — the solenoid valve controlling water supply to the tub. Inlet valve failure produces slow or incomplete fill, an E14 or E15 error code, or a valve that does not fully close and allows backflow. Valve replacement: $100–$180. (5) EcoSilence Drive motor assembly (800 Series and Benchmark) — the brushless DC motor assembly with ceramic bearings. Replacement required when bearing wear produces grinding during the wash phase or motor failure stops the wash cycle. OEM EcoSilence Drive motor assembly (not a generic Bosch motor): $220–$400. (6) CrystalDry zeolite mineral module (800 Series and Benchmark) — the zeolite drying container in the base compartment. Replacement required when zeolite absorption capacity exhausts (8–12 years of cycling); residual moisture on plastics after every cycle is the primary symptom. OEM Bosch zeolite module: $150–$280. (7) AquaSensor turbidity sensor — the optical sensor measuring wash-water clarity to determine rinse cycle duration. A mineral-scale-coated AquaSensor produces extended cycle times or an E9 error. Sensor replacement: $120–$220. (8) Control board — 500 Series: $220–$380; 800 Series (HomeConnect-compatible board required for Wi-Fi function on SHPM88Z75N): $280–$480. Board failure presents as programs that do not start, a unit that halts mid-cycle, or persistent error codes after component faults are resolved. HomeConnect Wi-Fi function requires a HomeConnect-compatible replacement board on 800 Plus and Benchmark models — a generic 800 Series board physically installs but disables app connectivity. (9) Door latch assembly — $80–$150. A failed latch produces a dishwasher that won't start, often displaying no error code — the control board simply does not register the door as closed. (10) Door gasket — $80–$150. Gasket degradation allows water to pool on the kitchen floor at the base of the door. Panel-ready Bosch installations (custom cabinetry panel overlays) require gasket replacement using Bosch's door-disassembly procedure to avoid panel bracket damage. (11) Spray arm (upper or lower) — $60–$120. A cracked or clogged spray arm produces spotty cleaning patterns on specific rack levels. NVA hard water accelerates mineral blockage of spray arm nozzles. (12) Third-rack spray manifold — $80–$160. The small upper spray arm assembly serving the third cutlery rack on 800 Series and Benchmark models; flow restriction here produces poor silverware cleaning in the third rack only.

Bosch 500 vs 800 vs Benchmark — series differences and service impact

The three Bosch dishwasher series sold in Northern Virginia differ in acoustic engineering, drying technology, and connectivity — differences that directly affect which repair components apply. (1) Bosch 500 Series (representative model: SHPM65Z55N, 50dB). Standard pump motor (not EcoSilence Drive), condensation drying (no CrystalDry zeolite), AquaStop hose assembly included. The 500 Series service profile is simpler: drain pump, circulation pump, inlet valve, AquaSensor, door latch, and control board. No EcoSilence Drive motor or CrystalDry module costs apply. 500 Series control board replacement ($220–$380) without HomeConnect firmware consideration. True replacement cost for Bosch 500 Series: $900–$1,300 installed in NVA. (2) Bosch 800 Series (representative model: SHPM88Z75N, 42dB). EcoSilence Drive motor, CrystalDry zeolite drying, HomeConnect Wi-Fi (app control via Home Connect app), AutoAir door (door cracks open at cycle end for steam ventilation), AquaStop hose. Additional service items versus 500: EcoSilence Drive motor assembly and CrystalDry zeolite module. HomeConnect-compatible control board required for Wi-Fi function on 800 Plus and Wi-Fi-enabled 800 models. AutoAir door hinge mechanism: $100–$200 if the door spring fails to crack open. True replacement cost: $1,200–$1,800 installed in NVA. (3) Bosch Benchmark (representative model: SHPM98W75N, 40dB). Same service profile as 800 Series — EcoSilence Drive, CrystalDry, HomeConnect. Additional: extra spray arm level, RackMatic adjustable middle rack with additional rack-height positions. Benchmark true replacement: $1,800–$2,500 installed in NVA. (4) Panel-ready configurations. All three series are available in panel-ready versions with a custom cabinetry panel overlay. Panel removal before service access follows Bosch's door-detach procedure — pulling the outer door without releasing the panel retainer damages the panel clip and the carrier frame. Repair time on a panel-ready Bosch is 15–25 minutes longer per visit; this is absorbed into the service call rate rather than billed separately. Pre-2020 Bosch 500 Series: verify control board part availability before authorizing repair — some SHPS88XT55N board variants have been superseded by updated part numbers.

Bosch dishwasher repair vs replace — the repair math

The repair case for a Bosch dishwasher is strong at virtually any age on the 800 Series or Benchmark, and solid on the 500 Series for all but the oldest units with multiple simultaneous faults. True replacement cost is the correct denominator — unit price plus installation. NVA installation for a dishwasher (disconnect, haul-away, reconnect, test run) runs $150–$300. Panel-ready Bosch installations with a custom panel overlay add $200–$500 for panel reproduction if the existing panel cannot be reused on a new unit. Bosch 500 Series: $900–$1,300 true installed replacement cost. A drain pump at $260 is 20–29% of replacement — clearly worth doing. A control board at $380 is 29–42% — at the upper bound of replacement cost on an older 500 Series, the one scenario where a second opinion on repair vs replace is worthwhile (particularly on a 500 Series older than 12 years where multiple components are aging). A drain pump plus control board at the same visit ($260 + $380 = $640) represents 49–71% of the $900 minimum replacement cost — replacement is rational here on a 12-plus-year-old 500 Series. Bosch 800 Series: $1,200–$1,800 true installed replacement cost. A drain pump at $260 is 14–22%. An EcoSilence Drive motor at $400 is 22–33%. A control board at $480 is 27–40%. Even a control board plus EcoSilence Drive motor ($880 combined) is 49–73% — approaching the 35% single-fault threshold only at the high end of a double-component repair on the least expensive 800 replacement. For all single-fault repairs, the 800 Series is clearly worth repairing at any age. Bosch Benchmark: $1,800–$2,500 true installed replacement cost. All repairs are well under 30% of replacement for any single fault. The repair case is decisive at every age. Panel-ready caveat (all series): a Bosch in a custom cabinetry installation where the panel overlay cannot be reused on a replacement unit changes the economics. A $400 panel reproduction added to $1,200 replacement becomes $1,600 — improving the repair case by 25% relative to the list price alone.

When to Call a Specialist

Homeowner-accessible Bosch maintenance: clean the triple-filter assembly monthly (lower rack out, twist and lift the cylindrical filter, remove the flat mesh filter, rinse under hot water), descale the spray arm nozzles with a pin or toothpick, and keep the salt reservoir filled in high-hardness water areas.
