Diagnostic Help

Condenser tumble dryer are relatively easy for most people fix if they are reasonably competent in DIY and working with electrical products as they really are rather simple appliances

This video can be used on all these makes of Condenser tumble dryer

Your Condenser tumble dryer is not heating? It Could Be One Of The Following:

  1. Heater fault.
  2. Cut out Thermostat faulty (TOC Thermal Overload Cut-out)
  3. Cycling Thermostat faulty
  4. Ntc fault if fitted faulty
  5. Air flow temperature thermostat faulty
  6. Pcb if fitted

Condenser dryers can be installed without the requirement to have a vent to the outside. However, it should be noted that these cannot be installed just anywhere and there are restrictions on temperatures and that cleaning filters regularly becomes essential. The moisture removed from the clothing during the drying process is condensed internally and the water vapour either drained to the house drainage system or collected in a container which has to be manually emptied.

low heat can be caused by one side of the heater not working or air flow problems

Thermostats & heater elements can be simply tested for continuity using an electrical meter. If the heater is open circuit it will require to be replaced, bearing in mind that many are in fact two elements for the different levels of heat, so check both circuits. If the heater is not open circuit and you have continuity then you should then look at the thermostats. Normally there are one of possibly two mounted around the heater housing but there are also often another one, possibly two, hidden on the vent or front of machine as you will see in this video there is one hidden in the drum, this is commonly known as the "exhaust stat" Air flow temperature thermostat.

Ntc sensors can be tested by using charts to measure resistance compared to the temperature see other videos on this.

    Hi, excellent video! I have the following zanussi –
    mod zdc68560w
    prod 91609680201
    Heating element is fine, just wondering if you knew where to locate the thermostat in this model. It seems it isn’t in the drum.
    Many thanks,

    hi Paul I have a Zanussi lindo 300 condenser tumble dryer which hasn’t done much work
    model ZDC 8202P
    product 916 097 379/00
    my problem is that it does not heat up at all
    I have tested the heating element and the thermal cut outs
    and also I have tried tipping water into the top with the draw removed and it does not pump
    even though the float switch is working
    I have removed the pump from the machine and tested it on the bench and it works
    the tumble dryer operates as it should other than getting hot
    could you please point me in the right direction
    could it be a circuit board fault and if so are these repairable?
    I am an electrician by trade and so have a basic working knowledge of electronics

    ps keep up the good work on your website very helpful well done
    many thanks rob
