Are Thermador and Bosch dishwasher codes the same?

Yes — Thermador Sapphire and Star Sapphire dishwashers are built on the Bosch platform (same BSH parent). E15 / E22 / E24 / E25 codes and diagnostic procedures are identical to Bosch.

What does E15 mean on a Thermador dishwasher?

E15 = AquaStop leak detector tripped (water in base pan). Tip the unit 45° to drain the pan, dry, then dye-test to find the leak — usually a sump gasket, drain-pump volute O-ring, or spray-arm feed tube. $245–$425 all-in. Don't reset and re-run.

Is a Thermador Freedom column worth repairing?

Almost always yes. A Freedom T36 / T42 / T48 column replacement runs $7K–$13K. Even sealed-system repair at $1,485–$1,985 OEM is under 20% of replacement.

Do you service Thermador in the Twin Cities?

Yes — factory-trained on dishwashers, ranges, ovens, cooktops, and Freedom built-in refrigerator / freezer columns. OEM parts only. Service across the Twin Cities luxury-home market (Lake Minnetonka, Edina, Wayzata, Kenwood, North Oaks).

How much does Thermador repair cost?

Most Thermador repairs land $345–$785 all-in. Dishwasher (same as Bosch) $235–$465. Oven sensor / latch $385–$585. Range igniter / spark module $345–$485. Freedom column gasket $485–$685. Sealed-system work runs $885–$1,985 OEM. The $149 trip fee is waived when you approve the repair.

THERMADOR · ERROR CODES

Thermador Error Codes Oven, Dishwasher, Freedom Column Faults — What They Mean

Thermador is the BSH luxury sister-brand to Bosch and Gaggenau — Sapphire and Star Sapphire dishwashers share the Bosch platform (so E-codes are identical), but Pro Grand / Pro Harmony ranges and Freedom built-in columns have their own fault sets. The Twin Cities calls we see most are dishwasher E15 (AquaStop), oven F-code panel faults, and Freedom column door-gasket / temperature alarms.

What we fix in Minneapolis

The Minneapolis repair mix

Sapphire and Star Sapphire dishwashers — Bosch platform

Thermador Sapphire and Star Sapphire dishwashers are built on the Bosch platform (BSH parent company). E-codes are identical: E15 AquaStop leak, E22 filter clogged, E24 drain blocked, E25 drain pump fault. Diagnostic and repair procedures are identical to Bosch — see our Bosch dishwasher error code page for the full breakdown.

Freedom built-in refrigerator columns

T18, T24, T30, T36, T42, T48 Freedom columns are 84" tall single-cavity built-ins (fridge OR freezer per column, paired side-by-side in luxury kitchens). Common Twin Cities calls: door gasket out of compression at year 8+ (gasket replacement $485–$685 OEM), hinge cartridge sag (re-shim or replace), evap fan failure (warm side, cold fan), defrost system (frosted evap coil). Sealed-system work runs $885–$1,985 OEM but a Freedom column replacement runs $7K–$13K — repair is almost always the right call.

Pro Grand / Pro Harmony ranges

Thermador Pro Grand 48" / 60" and Pro Harmony 30" / 36" / 48" ranges use the signature Star Burner with ExtraLow simmer. Most common faults: weak igniter on a burner (clicks but no flame — spark module or individual igniter), F1 oven sensor, dE / F5 door latch, F7 touch panel. We carry OEM Thermador igniters, spark modules, oven sensors, and door latches on the truck.

Thermador repair in the Twin Cities

Factory-trained on Thermador across dishwashers, ranges, ovens, cooktops, and Freedom columns. OEM parts only — Thermador build tolerances don't tolerate aftermarket. Service area: Lake Minnetonka, Edina, Wayzata, Kenwood, Lake of the Isles, North Oaks, Sunfish Lake, and the rest of the Twin Cities luxury-home market. 1-year written warranty.

From the truck

Field-service notes on appliance repair

On appliance repair, we keep the diagnostic tight because the failure catalog on this brand is well-documented. Well water in the outer western suburbs (Minnetonka, Wayzata, Orono) adds iron and manganese loading that plugs ice-maker inlet screens and dishwasher wash-arm nozzles inside 18 months without a softener.

Because this page focuses on sapphire and star sapphire dishwashers — bosch platform, our tech opens the call by isolating that subsystem before touching anything else. Wear parts (belts, pumps, igniters, valves) ship from our truck stock; boards and sealed-system parts are OEM-only from Marcone or the manufacturer's direct distributor. The $149 residential diagnostic is credited toward the repair if you approve; if you don't, you pay only the diagnostic and we leave a written scope. Every completed repair carries a 1-year parts and labor warranty in writing. The section above covers the specific failure surface — thermador sapphire and star sapphire dishwashers are built on the bosch platform (bsh parent company).

We stock the top-30 wear items for this brand on the truck, so most first-visit repairs close same-day. We're EPA 608 certified for sealed-system and refrigerant work, licensed and insured in Minnesota, and every tech carries a factory diagnostic laptop for brand-specific service modes. If the model is out of parts support, we'll say so on the first call and refund the diagnostic — that's the honest read on a repair-vs-replace decision, and it's the same read we'd give a family member calling about the same appliance.
