Heat pump tumble dryer – finding faults and error codes

by / Friday, 16 February 2018 / Published in Repair Guides

Finding faults and error codes on Aeg, Electrolux, John lewis, Zanussi Heat pump tumble dryers

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. E51
E = Error
X = alarm family
Y = alarm number

Alarm
description:

E21 - Tank drain pump triac failure.
E22 - Tank drain pump triac sensing failure.
E31 - Conductimetric sensing oscillation frequency too high
E32 - Conductimetricsensing oscillation frequency too low
E51- Motor triac failure.
E52 - Motor thermal cut off.
E53 - Motor triac sensing failure.
E54 - Motor jammed
E61 - Heating timeout
E62 - Compressor relay failure
E63 - Compressor automatic thermostat
E64 - Compressor sensing failure
E65 - Main Fan relay failure
E66 - Main fan automatic thermostat
E67 - Main fan sensing failure
E71 - Drying NTC1 failure
E72 - Drying NTC2 failure
E82 - Wrong selector reset position detection
E93 - Machine configuration error
E94 - Cycle Configuration error failure
E95 - Communication error between microprocessor and external EEPROM
E97 - SCF –CTF mismatch error
EB1 - Power supply frequency out of limits
EB2 - Power supply voltage too high
EB3 - Power supply voltage too low

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)

We hope this tutorial helped you get your tumble dryer working again!

    Hi, My dryer ( AEG Mod T76280Ac Prod no. 91609686000) shows error code EH0 quite often. Sometimes while drying, sometimes while turning after finished cycle. The manual says to turn it off and on and sometimes i need to wait a few minutes but it becomes normal again and usable.

    Any idea why this is happening?

    Thank you

    Dear Paul,
    We have a John Lewis Tumble Dryer, Condenser with Heat Pump. It doesn’t seem to be heating up. Following your video on this exact same model I have tried to get it into diagnostics mode but it won’t go. Holding down the Start/Pause and leer side button when the machine is on brings up an error message of E00. Any idea what I could do try try and see what is wrong with the machine. The machine is JLTDH18 with a product number 916 097 425 00 and Type number TC09H6MHP. Regards Paul

    Great YouTube site .. I have an AEG tumble dryer. Running fine until three days ago. A code EHO.
    I moved the machine so that I could try a different power socket. When plugged into a new socket the machine runs for 1 or even 2 full cycles before showing the same EHO code. I unplug for 30 seconds to reset and the same code appears. Unless I plug into a fresh socket! Very strange. I have had 6 new full cycles from the machine by using 2 different plug sockets alternately. Any idea what the underlying issue is? A sensor? Any help welcome.

    I’m only sorry i found this site after i got the part. Will be back when the next thing breaks…….

    Thanks again

    Hi, I have just used your video to dismantle my hoover dxc9dg-80 tumble drier as I have fault code e22. The video was brilliant however once cleaned and rebuilt it lasted 5 mins and e22 code back on. I couldn’t see a pump motor nor did the video show one. Is this code for the full tank switch or one of the 2 ntc switches?? I will purchase the parts from your site if I know what to buy. Many thanks

    We have a John Lewis JLTDC01 condenser heat pump tumble dryer which keeps getting an error message E50. could you please tell what this means and how to correct the fault

  17. Simon Mazengarb says : Reply

    We have a John Lewis heat pump tumble dryer JLTDH18. We get an E32 error code which is conductometric sensing oscillation too low. It this worth repairing?

  18. Claire Hughes says : Reply

    Hi, I have a John Lewis tumble dryer JLTDH18. The hinge on the door broke off so I bought a new part and replaced the door. Ever since then I am getting an ERR message when I turn the tumble dryer on and it just won’t start at all. I have unplugged the tumble dryer but this hasn’t helped.
    Do you have any suggestions what this error message might be due to please?
    Thank you!

    Electrolux dryer EDH3498RDE stops after 2/3 of process with E20
    after powering Off/On it’s working till complete

    B13-6B pump on the rear and level sensor is ok
    Google’s and Your’s err list doesn’t contain explanation of E20 🙁
