Good Morning, I have a customer with a Zanussi TCE7127W tumble dryer that runs for a while, then the bottom three lights on the display come on and the appliance stops and beeps, I have checked the error code and it states a E23 error code but that is not listed in the service manual. I cleared the error code and showed the customer how to read the code and told him toi run the appliance again till it error-ed out, he has just been on the phone and says it shows a E45 error code which is still not a listed error code. , has anybody any ideas before I refer the customer back to Zanussi. Heeeeelp
