Tumble Dryer Parts

it is very difficult sometimes to diagnose the problems with these heat pump tumble dryers.
I have included a video to show you the test mode sequence and also a PDF below which I managed to obtain.
but whenever you need parts for these dryers you will need to quote your model number and also the PCN number before we can do that you to the correct part

if you are still having trouble please contact us using your full model number including the product number for help from Paul

 

Finding your problem with a heat pump tumble dryer can be difficult on occasions as these tumble dryers dry the clothes using Refrigeration process.

These are some of the common error codes or faults

All dryers will show the alarm code on the time to end display.

The alarm will be shown as EX Y e.g. E51E = ErrorX = alarm family Y = alarm number

Safety first! Unplug the machine from the electrical supply and make sure the machine has been idle long enough so that the heater has cooled down.

 

Once a year vacuum the inside taking special care on the wiring, it is very important to clean all the vent tubes on a regular basis. Clean the heat exchanger (condenser dryers only)
