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 Mint Hill dishwasher leaves an orange film on dishes. Is it broken?

That film often comes from iron in well water rather than a dishwasher fault. Cleaning the filter and tub helps, and a water treatment specialist can address the source. If the unit also fills slowly, the inlet valve screen may be clogged and is worth checking.

Why does the dishwasher in our older Matthews home keep leaking after replacement?

Reused supply lines, an uneven opening or a drain hose that was not secured correctly are common causes. The technician checks the installation as well as the machine, so the real source gets fixed.

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.

Generations of Dishwashers Under One Counter

In an older home, a newer dishwasher may sit in an opening built for an earlier model, connected to plumbing and wiring that have been reused through several replacements. Kinked drain hoses, worn supply connections and loose mounting brackets are common, and they lead to leaks and poor draining rather than an outright failure of the machine.

On properties served by private wells, iron and sediment can leave a reddish or gritty film in the tub, clog the inlet valve screen and dull the spray arms. A whole-house sediment filter is a plumbing question, but the dishwasher symptoms are ours to sort out.

Safe First Steps and the Service Visit

Turn off power at the breaker, clean the filter assembly, and make sure the spray arm holes are clear. Check under the sink for a damp cabinet floor. We test the pump, valve, float and controls, explain what failed, and give the price before work. If the unit is still under manufacturer warranty, we will mention it.
