This is most likely a faulty heating system, to confirm you said the when on wash its only performing a cold wash, and when on drying its not heating the clothes?
If thats the case it points towards a faulty PCB or NTC (heat sensor) since there are two heating elements (one for heating water, the other for air), so you should have a fault on both heating elements.
Are any lights flashing, or any sign the machine is in a error state (does it complete its full cycle\programme)?
Hi Angela, you can disregard the options for calls they are just automated messages.
Based on the age of the appliance, I think I would be inclined to put the money towards a replacement, you looking at least £100 in parts and labour to change the NTC, and upwards of £200 to change the PCB.At this age you will start to find other faults with motors and pumps, if you are keen to retain it, I would suggest a repair and protect plan from D&G, they normally charge about £15 a month, which covers this one off repair and then gives you a further years warranty for any further breakdowns, details about this plan can be found here.
Please let me know if I can be of any further assistance.
