Common Thermador Dishwasher Error Codes
Not every code means a repair bill. Seven of these twelve Thermador dishwasher codes are usually something you can clear yourself; the remaining five involve a part inside the unit.
Thermador Dishwasher E15
Usually needs a technician
What it means: A safety float has sensed water pooling in the bottom of the tub and shut the cycle down to stop a leak spreading.
Why it happens: Water reaches the base when something above it leaks — a seal, a hose connection, or the tub. The code is the safety system working, not the fault itself.
What you can check: Stop using the machine and turn its water supply off at the valve. The pump may keep running while the float is raised, which is expected.
When to call someone: This needs a technician — the code says water is where it should not be, not where it came from.
Thermador Dishwasher E24
Often clearable without a technician
What it means: The dishwasher cannot drain, with the blockage somewhere between the filter and the air gap.
Why it happens: A packed tub filter, a kinked drain hose, a loose pump, or a silted-up air gap on the worktop.
What you can check: Clear the tub filter first, then check the air gap if your sink has one, then the drain hose for kinks. Those are the three reachable points.
When to call someone: If all three are clear, the pump itself needs looking at.
Thermador Dishwasher E22
Often clearable without a technician
What it means: The filter, drain pump, hose or air gap is clogged enough to stop the machine draining.
Why it happens: Debris from the tub works into the drain path; an air gap on the worktop can silt up independently.
What you can check: Clear the tub filter first, then the air gap, then check the drain hose for kinks.
When to call someone: If the filter and hose are clear and it still will not drain, the drain pump needs testing.
Thermador Dishwasher E25
Often clearable without a technician
What it means: The drain pump is blocked or loose, the hose is kinked, or the air gap is clogged.
Why it happens: The same drain path as E22, but pointing more squarely at the pump end of it.
What you can check: Clear the tub filter and check for anything visible jamming the pump underneath it, then check the hose and air gap.
When to call someone: If nothing is visibly jamming it, the pump needs testing or reseating.
Thermador Dishwasher UP
Often clearable without a technician
What it means: Not a fault — the dishwasher has finished installing a software update.
Why it happens: Connected models update themselves; this is the confirmation, not a problem.
What you can check: Dismiss it and use the machine normally.
When to call someone: No call needed.
| Code | What it means |
|---|---|
| E12 | Hard-water scale has built up inside the heat pump component and needs descaling. |
| E16 / E17 | The machine is having trouble getting water to flow in properly during the fill stage. |
| E18 | Water isn't filling to the right level, or the pump isn't circulating water correctly. |
| E23 | The drain pump is obstructed, clogged, or has failed outright. |
| E27 | The household electrical supply voltage reaching the dishwasher is lower than what it needs. |
| E04 | The machine's own self-test found a fault in the heater electronics. |
| E14 | The flow meter has failed, or water is not entering at the rate the cycle expects. |
| E0110 | The internal electronics have stopped communicating with each other. |

Common Thermador Dishwasher Problems We Fix
Not Draining Water
Clogs in the drain line, filter blockages, or a faulty drain pump prevent water from emptying after the cycle. The independent local provider Severna Park Appliance Repair connects you with will diagnose the cause and clear the obstruction or replace the pump.
Dishes Not Coming Clean
Poor cleaning results often stem from a worn spray arm, clogged nozzles, inadequate detergent, or a malfunctioning wash motor. A local provider will inspect your Thermador dishwasher's spray system and mechanical components to restore proper wash performance.
Won't Start or Fill
A faulty door latch, broken fill valve, or electrical control issue can prevent the dishwasher from initiating a cycle. The independent provider you're connected with will test the inlet valve, door mechanism, and control board to pinpoint and repair the fault.
Loud Noise During Wash
Grinding or rattling sounds typically indicate a worn pump, loose spray arm, or foreign debris inside the tub. Local Thermador dishwasher service providers will inspect the internal components and replace worn parts that are causing the noise.

Call (410) 469-6648Thermador Dishwasher Repair Across Severna Park
Severna Park's water supply, sourced from deep aquifers serving Anne Arundel County, carries naturally elevated mineral content that accumulates over time inside appliances. Thermador dishwashers, built with precision spray arms, fine filtration, and sensitive wash cycles, are particularly vulnerable to scale buildup that reduces spray force and water flow. In neighborhoods like Arundel Beach and Olde Severna Park, where homes have been in place for decades, the cumulative mineral deposits inside these machines can become pronounced without regular maintenance and professional cleaning.
Electrical disturbances from the region's severe summer thunderstorms and winter nor'easters create another pressure point for Thermador dishwasher electronics. Power surges can damage control boards and sensor circuits without destroying the motor, leaving owners with a unit that starts but fails mid-cycle or locks in error mode. Local independent repair providers understand how these regional water conditions and weather patterns affect Thermador performance and can diagnose whether a machine needs descaling, sensor replacement, or board-level repair—getting your dishwasher back to reliable operation.

Each independent provider sets their own pricing structure, including any service call fee. Ask for an estimate before authorizing work so you know what to expect.
Clear the area around your dishwasher so the technician has easy access underneath and behind the unit. If water damage is present, have towels ready.

Hard water in the Severna Park area can cause mineral scale buildup inside your Thermador Dishwasher over time, reducing performance. Run rinse-aid to combat this, clean the spray arms regularly, and wipe door seals to prevent mold. Avoid overloading and use the correct detergent type for your water conditions.
Power surges from severe thunderstorms and winter weather events can damage dishwasher control boards and electronic components. Consider using a surge protector or whole-house surge protection if your appliance has experienced repeated electrical issues.
