I have an aeg heat pump dryer and on diagnostic mode shows an error code of E58

Error code E6H on your AEG Lavamat washing machine typically indicates a problem with the heating system. It may mean that there is a problem with the heating element, the temperature sensor, or the control board. It's best to refer to the manual for your specific model for the exact meaning of the error code and for further instructions on how to resolve the issue.
If you are unable to resolve the issue yourself, it is recommended that you contact a professional repair service for assistance. Attempting to repair a washing machine can be dangerous and may void your warranty if not done properly.

I don't believe that there is any refrigerant gas involved with this machine, but can't find any details on the heat source for it. They all work from a heating element of some sort. Have you checked the heat exchanger and filters for blockages? That is where your issue is likely to be. Also check the intake grill on the bottom right side kickplate. The way condensing dryers is very simple. Cold air is sucked into the bottom of the machine and passes over the outer surface of the heat exchanger / condenser unit. The air is then heated by an element and blown through the dryer drum and the clothes. The hot moist air is then blown through the inner fins of the heat exchanger and because the unit has been chilled at the first stage entry, the steam condenses back to water.

If you open it up you should find the tech sheet on your dryer. It will explain how to put it diagnostic mode, then you can test the door switch and see if it's not the problem. My bet it's the belt.

The problem when the dishwasher does not heat is failure which requires to remove the qualified personnel and therefore error code is not shown on the display but it is visible in the service mode.

Possible error causes:
faulty heating element
wiring between heating element and PCB
PCB (printed circuit board)

Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly. if you dryer is gas check out this gas no heat tip.... If you have an electric dryer, you can have many differentthings that can go wrong causing the dryer not to heat. check outthis electric no heat tip...

This error code means your water sensor has detected a leak. it will stop when the sensor is dry.
Try getting the water out of the trap door and letting the machine dry.

I would also unplug it for secirity reasons.

Basically your water pump is getting tired or the sensor is dirty. Try cleaning the sensor or else you may have to change the pump.
