# Miele dishwasher heating & drying repair

### Two conditions, not one

The heating circuit and the temperature sensor that watches it are reported separately by this make, and that separation is worth using: a drifting sensor makes a perfectly good heater look failed, and it is a fraction of the part.

### What actually goes wrong

- **The rinse aid reservoir**, empty. Free, and the commonest cause of wet dishes.
- **The door not opening at the end** on the machines built to do it.
- **The temperature sensor**, drifting.
- **The heating circuit**, which is the part this row is priced for.

### Scale, again

A heating element coated in scale heats badly before it fails, and in this water it will coat. That is one more reason the salt reservoir and the water hardness setting are worth getting right — they are protecting this part.

What this involves

Heater and sensor tested separately, as the machine reports them

Drying checked before anything is called a failure

Rinse aid and door-opening behavior confirmed first

Establish whether it is heat or drying

They feel the same in the kitchen and they are different systems. Dishes that are wet but clean, on a machine whose cycle ran the right length, is usually not a heater at all.

The free checks

Rinse aid reservoir, whether the door is opening at the end of the cycle on the machines that do that, and how the load was packed. Between them they account for most "it will not dry" calls on this make.

Read the two conditions apart

The heating circuit and the temperature sensor have separate numbers here. A sensor reading wrongly makes a working heater look failed, and it is a much smaller part.

Measure, then replace

A resistance at a temperature, and a current under load. Both before anything is ordered.

### Miele dishwashers do not have a drying element, do they?

Not in the way an older American machine does. They dry with residual heat, and the newer ones open the door at the end of the cycle to let the moisture out. So a machine that will not dry is often a door that is not opening or a rinse aid reservoir that is empty, and neither is a repair.

### Everything is clean but the plastics are wet.

That is normal on a residual-heat machine and not something to fix. Plastic holds less heat than china or glass, so it dries last and sometimes not at all. Rinse aid helps more than anything else.

### The water never seems hot.

Then it is worth measuring rather than judging by hand — a Miele runs cooler than people expect on the eco programs by design. If the machine reports the heating circuit or the sensor, that is a real condition and it is on this page.
