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.

Why are my dishes gritty on well water in Clover?

Sediment in the water is the likely cause. It can clog the filter, the spray arms and the inlet screen. Clean those first, and if the grit continues, consider a sediment filter for the house.

Our Lake Wylie dishwasher won't drain after we were gone a month. What happened?

Food residue may have dried in the filter or drain, or the drain pump may be sticking after sitting. Clean the filter and run the disposal if the dishwasher drains through it. If it still won't drain, we test the pump.

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.

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 rural water

Dishwashers on private wells around Clover face sediment and iron that clog the inlet valve screen, coat the spray arms and leave a gritty film on dishes. A slow fill, weak spray or rust-colored residue in the tub are typical signs. Cleaning the spray arms and the filter at the bottom of the tub helps, and a whole-house sediment filter kept on schedule protects the valve.

If a dishwasher on well water stops filling entirely, the inlet valve may be clogged beyond cleaning or stuck shut. Turn off the dishwasher's breaker and the supply valve under the sink before pulling the kick plate to look for drips. Replacing the valve is a common, moderate repair, and the technician will also flush the line so the new screen does not clog on the first cycle.

Idle machines in lake homes

A dishwasher that sits unused for weeks can develop dried seals, a stuck float or a pump that hesitates at startup. Before leaving a Lake Wylie home for a while, run a quick rinse cycle and leave the door slightly open. If it will not start, drain or fill when you return, we test the pump, valve, float and controls, and we give you the price before any work.
