Thermador occupies a distinct position in Northern Virginia's luxury appliance landscape: the brand that pioneered the American professional-style range, and that today produces the ProGrand — one of the few dual-fuel freestanding ranges in its price class with a genuine commercial-grade Star Burner system. Thermador is owned by BSH Home Appliances Group (the same parent company as Bosch and Gaggenau), which means its dishwashers, some refrigerator components, and the electrical architecture of its wall ovens share engineering DNA with those brands. For service, that's important: Thermador faults that look brand-specific often follow BSH platform patterns familiar to technicians who also work on Bosch and Gaggenau.
Thermador ProGrand and Pro Harmony range repair
Thermador's ProGrand ranges (36-inch and 48-inch dual-fuel, priced $5,500–$9,000 new) are the most commonly serviced Thermador appliance in Northern Virginia. The faults we see most frequently: (1) Star Burner igniter failure — Thermador's Star Burner uses a six-point burner head with a proprietary igniter geometry that produces a ring of ignition around the burner perimeter. The igniter module is Thermador-specific; generic igniters do not fit or perform correctly on the Star Burner platform. A failed Star Burner igniter produces a burner zone that clicks without lighting, or that requires multiple ignition attempts before catching. Igniter replacement (per zone): $250–$480. (2) ExtraLow simmering module — the ExtraLow system reduces the burner to a true simmer at temperatures competitors' burners cannot sustain. The bimetal module that achieves this fails after 8–12 years of regular use and produces a burner that cannot simmer below medium-low without cycling off. Replacement: $180–$350. (3) Oven temperature sensor (RTD probe) — a failed sensor causes the oven to overshoot or undershoot temperature, or to display a fault code. Sensor replacement: $180–$320. (4) Control board — Thermador's ProGrand uses a BSH-platform control board; replacement $480–$900. (5) Convection fan motor — bearing wear produces audible noise before failure; complete failure results in heat stratification inside the oven cavity. Replacement: $220–$380. The Pro Harmony range (30-inch, $3,800–$5,500) uses the same Star Burner platform on a more compact footprint with the same service profile.
Thermador wall oven, induction cooktop, and refrigerator repair
Thermador's wall oven lineup — the MES (single electric, $4,500–$7,500) and PODS/POSC (double, $7,500–$12,000) series — uses the BSH control platform with Thermador's Genuine European Convection system. Common wall oven faults: (1) Bake element failure (electric models) — replacement $200–$380. (2) Convection fan motor bearing wear — replacement $220–$380. (3) Control board — BSH-platform board, $550–$950. (4) Door gasket — $120–$250. (5) Temperature sensor — $180–$320. Thermador Freedom induction cooktops (30-inch and 36-inch, $3,200–$5,500) use a Booster zone system that delivers the highest output of any residential induction zone at 3,700 watts. Common faults: (1) Induction zone inverter failure — the inverter for a Booster zone that's lost power or is producing E-codes; $280–$520. (2) Glass top replacement — deep scratches or star cracks from dropped objects; $400–$800 for the glass panel. (3) Control board — $480–$880. Thermador refrigerators (T18/T24/T30 columns, built-in French door models) use BSH refrigeration platform components. Common faults: condenser fan motor ($180–$320), evaporator fan ($160–$280), sealed system faults ($400–$900), control board ($320–$600).
Thermador DWHD dishwasher repair
Thermador's DWHD dishwasher lineup (DWHD560/630/660/860 series, $1,800–$2,800 new) is built on the BSH premium platform — the same engineering base as Bosch Serie 8 and Gaggenau DF dishwashers, with Thermador-branded control architecture. This means the fault profile and many components follow Bosch patterns: (1) Drain pump motor failure — the most common Thermador dishwasher service call; drain pump replacement $200–$380. The E24 drain error code indicates this fault. (2) Circulation pump bearing wear — produces a grinding noise during the wash cycle; replacement $280–$480. (3) Control board — Thermador DWHD boards use BSH platform firmware with Thermador-specific part numbers; replacement $380–$680. (4) Water inlet valve failure — E15 water intake error (base flood protection); inlet valve replacement $160–$280, but if the base tray flooded, the tray must also be drained before restart. (5) Door latch and damper assembly — DWHD dishwashers are typically panel-ready; the damper absorbs the weight of a custom cabinetry panel. Damper fatigue after 8–10 years: $140–$280 for the damper assembly. Thermador DWHD dishwashers have a design life of 12–16 years. Parts availability is strong through BSH's distribution network for all current-generation DWHD units.
Why Thermador repair requires a specialist — the Star Burner difference
Three aspects of Thermador service distinguish it from standard appliance repair in Northern Virginia: (1) The Star Burner is proprietary. Thermador's Star Burner is not a modified version of a generic burner head — it is a distinct burner design with a six-point star geometry, a specific igniter gap, and an ignition pattern that requires OEM Thermador parts. A technician who replaces a Star Burner igniter with a generic aftermarket part produces a burner that may light but will not perform correctly at high BTU or sustain the ExtraLow simmer range. (2) The ExtraLow simmering module requires correct diagnosis. The bimetal ExtraLow module is a wear item that most generalist technicians don't encounter. Its failure presents as an inconsistent simmer — the burner cycles off under a certain heat level — which can be misread as a gas valve fault. Correct diagnosis saves a $250–$480 gas valve replacement when the actual fault is a $180–$350 bimetal module. (3) BSH platform boards span three brands. Thermador, Bosch, and Gaggenau share a common control architecture, which means an experienced BSH-platform technician can diagnose a Thermador control board fault using diagnostic patterns that cross all three brands. This reduces misdiagnosis on board faults and lowers the rate of unnecessary board replacements.

Frequently Asked Questions
How much does Thermador appliance repair cost in Northern Virginia?
Thermador appliance repair in Northern Virginia typically costs $150–$900 depending on the appliance and fault. Star Burner igniter (per zone): $250–$480. ExtraLow simmering module: $180–$350. Oven temperature sensor: $180–$320. Control board (range or oven): $480–$950. Convection fan motor: $220–$380. Dishwasher drain pump: $200–$380. We provide a written upfront quote after the diagnostic before any work begins. 90-day workmanship warranty. Call (571) 571-1664.
My Thermador Star Burner won't ignite — what's wrong?
The most common cause is a worn Star Burner igniter module. Thermador's Star Burner system uses an OEM-specific igniter that produces ignition around the six-point burner perimeter. Igniter failure causes the burner to click repeatedly without lighting, or to require excessive cycling before catching. Igniter replacement per zone: $250–$480. The second common cause is a failed ExtraLow simmering module, which affects only the simmer behavior, not full-BTU ignition. A same-day diagnostic determines which component is at fault. Call (571) 571-1664.
Is my Thermador dishwasher showing E15 or E24 — is it serious?
E24 is a drain error and typically indicates a drain pump motor failure ($200–$380) or a blocked drain path. E15 is a water inlet / base flood protection error — the dishwasher has detected water in the base tray and locked out. For E15, the base tray must be drained before the dishwasher will restart; the inlet valve may also need replacement ($160–$280). Neither code indicates a major structural problem. A same-day service call identifies whether the fault is the pump, inlet valve, or control board. Call (571) 571-1664.
