Why does my Thermador dishwasher stop and won't drain or start?

Often water has reached the base pan and triggered the float switch. That shuts the cycle down to prevent flooding. We find the source of the leak, dry the base and reset the system.

After a thunderstorm my Harrisburg dishwasher's lights flash and it won't start. What should I do?

Turn off its breaker for a full minute, then restore power and try a short cycle. Many controls recover from a surge that way. If the error returns, a board or sensor may have been damaged, and we can test it during a visit.

Do you repair dishwashers in Concord townhomes where the unit is tight under the counter?

Yes. We slide the dishwasher out carefully to reach the water line, drain and wiring, then reset and level it when the repair is done. If the mounting brackets or the water connection are part of the problem, we point that out too.

Thermador Dishwashers: What We Check First

Thermador dishwashers, including the Star Sapphire and related lines, are built on the same BSH engineering platform as Bosch dishwashers. They use a cylindrical filter in the base, a drain pump below a small cover, a circulation pump with an integrated flow-through heater, and a leak protection system with a float switch in the base pan. Many models offer StarDry, which uses a mineral called zeolite to help dry dishes, and third-rack cutlery storage.

Base pan float tripped by a hose, seal or suds leak
Circulation pump and heater assembly failing to heat water
Drain pump impeller jammed beneath the filter cover
Weakened hinge springs under heavy custom door panels

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our Thermador dishwasher repair guide.

Drains, disposers and storm-tripped controls

Most dishwashers here drain through the garbage disposer or a high loop under the sink. A disposer installed without its knockout plug removed, a clogged air gap, or a drain hose kinked behind the cabinet will leave water in the tub. Inside the machine, the filter at the bottom collects food and glass bits, and a neglected one causes poor cleaning long before anything breaks.

Concord and Harrisburg homes on city water rarely deal with the sediment that wells bring, but summer thunderstorms are another matter. A flicker of power can leave a newer dishwasher frozen mid-cycle or flashing an error. Turn the dishwasher's breaker off for a minute, turn it back on, and run a short cycle. Clean the filter while you wait.

If that does not clear it, the technician tests the drain pump, inlet valve, heater, door latch and control board. Builder-grade dishwashers in newer subdivisions are generally worth repairing when the problem is a pump or valve, and we will tell you when a cracked tub or a failed board on an older model points toward replacement instead.
