RH8CTD701 Turning off after a few minutes

[Tez911]

Hi all i have a Russell Hobbs RH8CTD701, was working fine went on holiday and had niece looking after house, when we got back it was clear the filters had not been emptied so i cleaned it all out including the pioes that feed the the water collection at the top. But everytime i use it it stops after a couple of minutes. It will actually turn off then after about a minute the display comes back on. Have changed the heater assembly at the rear including all sensors attached to it. Any help would be appreciated i cannot afford a new dryer.

Strange there’s no error code but here’s the service test stuff for it, you need to give it five seconds at least when changing through them.

have you checked the socket ?

try running it in a different socket outlet

Where it says sw2? attached are the buttons I have on machine.
I have tried another socket with same results but the both sockets are on the same spur. Would it be safe testing through a extension?

yes as a short test you can use an extension lead. make sure its rated at least 10 amp and unwound

the way you are talking all the power goes off the machine ( no lights at all) for about 60 secs

does sound like a power issue. as soon as the heater comes on the power drawn by the machine heats something up that switches off the power

this can be internal or external to the machine , could even be the plug on the lead. have you checked that for signs of getting hot ?

Manage to get it in service mode, first thing to flag up was E05 and I ordered the sensor that sits just under the filter. Replaced today still same issue. The plug does get warm but wouldn’t say its too hot. I have replaced the lead and plug in the past as the one melted. I will try and test on another socket thus weekend. Thanks for the reply

[electrofix]

when you say you replaced the lead and plug is it a moulded plug on the new lead
if yes suspect that till you prove otherwise
you would have to do a continuity check on the lead after it fails

Dave

[Tez911]

Yes it is a moulded plug, replaced like for like. Will hopefully get time sunday to check

[Tez911]

Tested on extension today from another socket did exactly the same also checked continuity on earth live and neutral from plug to the suppressor filter on fail and all passes. Think at this point im going to pull pcb out and look for obvious damage
