Hot point Aquarius WDL540 Fault

Re: Hot point Aquarius WDL540 Fault

Only the bottom five lights are used for error codes.

If you have used the dryer without checking or cleaning out a blocked filter as advised it will fail swiftly.

The machine runs a diagnostics check and if it finds any faults it will not run, just go into error mode.

I think it was used on a 40min dry, which is most likely the cause for it going again. I will attempt to clean the condenser filter, can you advise how to do this?

Also, I tested the thermistor in the dryer housing and couldn’t get a resistance reading from it, what should it be?

Thanks again.

Re: Hot point Aquarius WDL540 Fault

The resistance of any thermistor varies with temperature, for this one you should see,
@ 0°..36000 ohms
@25°..12000 ohms

No hard and fast rules for removing the condenser, you just have to follow your nose. 😉

Re: Hot point Aquarius WDL540 Fault

I tested the thermistor and it’s working so I went ahead and fitted a second replacement dryer element.

Have done three washes without drying successfully. Just tested the dryer with the lid off and can’t here or feel the fan going round (by feeling or observing the spindle which protrudes slightly from the top casing) within a minute or so of the cycle starting so I cut the power (also the blower housing is very hot).

My suspicion is that the blower motor could be knackered, it has continuity when tested with multimeter. I tried applying 12v to it and it moves fractionally but I’m assuming it needs AC current to operate.

Can you offer any advice as to how I can test it?

Thanks, Alex.

Re: Hot point Aquarius WDL540 Fault

Yes, you will have to completely remove the dryer housing and physically check that the motor/fan will spin freely. This would be as good a time as any to check/clean the condenser filter whist you have the dryer assy off. 😉

Re: Hot point Aquarius WDL540 Fault

I’ve done all that, I cleared away loads of fluff and fan spins freely, also has continuity however when I observed it at the beginning of the dryer cycle it didn’t spin up, is there another way I can test the fan without applying AC current to it?

Re: Hot point Aquarius WDL540 Fault

Ps. I also flushed the condenser out with cold water and debris did come out which could have been blocking the filter.

None of the trade members would advocate live testing of any kind, as for ‘applying AC current’ any mention of such practise would lead to a refusal to continue to offer help on this matter. :rolls:

With the main plug out a continuity test of the wiring from the fan motor to the main pcb would be advisable. The fan motors are not a common failure but it does happen.
