Hi all,

My Renlig DW60 (underneath an Electrolux 911D53-0L, which I believe is also known as a F35020VI) has stopped drying - there is no hot air escaping when you open the door at the end of the cycle and the contents are cold and still quite wet.

However, if opened mid-cycle then steam does escape, i.e. the water cannot be cold at that point.

Are there separate heating components for water and dryer - and if so is it likely to be the latter?

Thank you!

Yes, separate. Dryer element has likely over heated and tripped to protect itself. Thermal trip will be in the element air duct, a two terminal device, which might or might not be resettable. Dust and fluff may need cleaning out to improve the airflow.
 
I think it might need more knowledge and experience than I can give it unfortunately.

Looking at spares, assuming the details are correct, there are two heating elements in this model:

It is not clear what each does. This video talks about the replacement of the former fixing a cold water problem, but my water does heat up (although according to a Bluetooth thermometer, maybe not enough - 51 degrees during a 60 degree wash - maybe a thermostat problem, as surely heaters either work or not?). He ultimately identifies an issue with the circuit board.

There is also an "active drying air guide" but I can't find any details of what it does.

In short, slightly unclear symptoms and too many variables in terms of potential problem parts mean I think I need to find someone to look at it, unfortunately!

It's a Dishwasher not a Washer Dryer, just the one flow thru element.
 
So if it heats the water to wash (steam when opened mid-cycle) but doesn't dry any more (no steam, stone cold at end of cycle), what's the problem?

Yes, I realised that later, the op just mentioned 'washer'. Same applies though - if the op is not up to testing, he will have to refer it to an engineer.

I have not delved into the drying aspect of our washer, all I can say is when we take things out they are mostly cold and mostly dry. Open the door near the end and I will be met with a lot of heat and steam, which might be a drying cycle.

You have obviously found it has two possible replacement elements, the semi circular one will likely be the water heater one, the one in the tube the heated air element - the latter being the one which is failing to get hot.

I have an electrolux dishwasher that had a similar problem. It was the relay on the control PCB intermittently not working (High resistance on the contacts). I replaced the relay and all is now working... You don't need to remove the dishwasher to get to the pcb, just remove the front panels.
To test you will need a multimeter and power supply to fire the relay.

I'm not sure how the dishwasher dries with that tube heater but its the only one I could find in mine. I assume it heats the water to near boiling on the last rinse?

Not saying you are wrong, just curious as to how that might work....

It heats water passing through that unit to do the wash, having done the wash - it must get a fresh quantity of clean water hot to do a final rinse, they final rinse gets the crockery really hot evaporating the water. Is that how it works?

If so, then it doesn't really help the op - the heater element must be OK if it is heating the water for the wash, it is failing the last stage above.
 
Thank you everyone for your thoughts on this one - really appreciated.

It does appear to be an intermittent fault, as a 70 degree wash today seemed to work; I used a Bluetooth thermometer to test it (and also noted steam escaping at the end of the cycle):

On that basis I think @SpecialK is on to something - and it is music to my ears to hear it might be fixable without removing the whole dishwasher as the way it's been installed (floor put down afterwards) was going to make that a right pain.

These are the relays I ordered to replace them - https://www.aliexpress.com/item/32970489519.html

I may have a spare one somewhere if you get desperate...

Thank you - very helpful and appreciate the offer!

All seemed to be well since my last post until I noticed an unusually loud humming coming from it the other day and it's not getting up to temperature again (confirmed by Bluetooth thermometer). I'll start with the relay.
