Beko DCU7230W Condenser Tumble Dryer trips electrics

[Twoten]

I have looked at the above dryer (Prod Code: 7182681500) which had started to trip the electrics.
Testing has found an insulation fault in the element which can be dried out.
The fault appears to be due to condensation in the heater area. I have Cleared the drain channel, pump impeller, checked and cleaned the fan. Cleaned the condenser and tested.
The machine appeared to be OK for 2 months but has started to trip the electrics.
Is there anything I may have missed that would cause condensation in the back panel and heater that I may have missed?

is it anywhere where there is a draft that could cool the rear panel and cause it ?

are they using half heat ?

Could it be when the customer is using the time delay option? The heater are gets pretty wet with washing left in the drum.

No, I don’t think so.
As far as I am aware the machines have been in the same position for some time. Also, the problem first occurred a couple of months ago when the weather was quite hot.

i assume when its running the temp inside is high enough

I’ve not considered that, would it cause this issue?.
If not hot enough, would it generate enough steam and would the condenser not be cool enough to condense the moisture preventing the condensation in the heater area?
What should I expect the operating temperature to be and where would it be tested?

[electrofix]

if its not hot enough it would more likley drop moisture after the condensor ( assume you have checked for airflow both ways through the condenser )

if the air is hot it will carry the moisture on through the heater and back into the drum. Also if the condenser is working properly the heat of the air will dry out any moisture in the heat duct

Good point, I will check.

The condenser was flushed out in both directions, All vent ducts were clear.
