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.

Our Peachland dishwasher leaves a gritty film. Is it broken?

Not necessarily. Grit usually comes from well sediment or a clogged filter. Clean the filter and check your whole-house filter first. If the film continues, we can check whether the inlet valve screen is restricting water.

Rust stains appeared in our Polkton dishwasher. Is the tub rusting through?

Usually the color comes from iron in the water, not from the tub. Stainless and plastic tubs do not rust that way, though chipped racks can. We inspect the tub and racks and tell you plainly what we find.

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.

Sediment, Iron and the Dishwasher Inlet

Well water around Peachland and Polkton can carry fine sediment that settles in the dishwasher's inlet valve screen. As the screen clogs, the dishwasher takes in less water and dishes come out with a gritty film or food left on. Iron may leave rust-colored stains on the tub, racks and dishes, even when the dishwasher itself is fine.

Start with the parts you can reach. Turn the dishwasher off at its switch or breaker, remove the bottom rack, and rinse the filter at the base of the tub. Check whether a whole-house filter is overdue for a change, since a clogged one can lower the pressure reaching the kitchen. If the house has a water softener or iron filter, confirm it is working.

Our technician measures the fill, inspects the inlet valve, tests the drain pump and wash motor, and looks for leaks under the tub. If the valve or a pump needs replacing and is not on hand, we tell you the timing and the price before ordering.
