Beko DSC85W only gets clothes luke warm

problem now is you seemed to have changed everything but you may have damaged new parts by getting the fault wrong

Yes, there was a flash/pop when my wife started the dryer and when I took the top off and front panel where the flash/pop was there was scorch marks on the plastic and the board, I replaced the board, as soon as the plug was put in and switched on the RCD flipped. After checking online it looked like it could be

interference filter, this was replaced (I only just remembered this next bit) and when connected BUT NOT SCREWED TO THE MACHINE it didn’t flip the RCD and the dryer switched on and seemed fine.

After this I attached the filter to the machine, put the dryer back together again and moved it back into place. It was then filled and switched it on and then the RCD flipped!!

After removing the washing and the top of the machine I unplugged the filter and checked it and it looked fine so I put it back on but didn’t screw it to the back of the machine and when the power was put on it was fine! I then attached the filter to the machine again and it flipped the RCD.

So again another amazing google and it then looked like the heater can cause this if its blown/faulty and might have been going since the first front NTC went.

New heater was ordered and replaced and all hooked up with filter to machine and RCD didn’t flip and dryer seemed to be working fine BUT still no heat and again no heat on engineer test as explained.

As you can guess I’m no expert and mainly rely on google/youtube to have a go and waste my hard earned cash but I’d rather try than just throw kit away and I usually learn something from most jobs I do, even if this one might be BUY A NEW DRYER and disconnect access to google and youtube!! 😉

All help is appreciated

Cheers

Yeah im coming to that sinking feeling Dave!! Ah well better sell some art!! 😉

Dave, cant I go through tests on each part that I have replaced to see if they give the right readings and back track it from there? Not sure on how to test a board though?

[Specialist01269]

If as you say the RCD trips when you screw the filter back in place, this would be a good place to start. Obviously this shouldn’t happen. POWER OFF WHEN CHECKING PLEASE. Your not going to like this, but isn’t it time to admit defeat now ?. Your just going around in circles and as Dave rightly said, you may well have done other damage now and there’s only so much we can do without being able to see and test the machine.

[GingaPete]

Yes this did flip before I replaced the heater and not doesn’t with new heater on. I’m fine and no worries with accepting defeat if its a lost cause its a lost cause 😉 Yeah I get what Dave said no worries all round 🙂

[electrofix]

you say the machine was blowing the rcd

did it blow the rcd after you changed the main board

and was the heater changed after the main board ?

the order in which things happened and what parts you replaced and when can have a huge bearing. if the heater ntc was blowing the rcd then changing the panel before curing the heater may damage the panel

Hi Dave: If you look at post 32, it says that the mains filter was changed but when screwed back to the machine the RCD flipped. Without the filter fitted then the RCD was fine, the wonder of Google then said the new was faulty. Way back when in the posts the op said that he’d replaced the PCB, my reading of that (may be wrong) is that the heater has only just been changed and the PCB replaced a while back.

[GingaPete]

you say the machine was blowing the rcd = was tripping yes

did it blow the rcd after you changed the main board = yes this only happened after the new board went in

and was the heater changed after the main board ? = yes once the heater was changed there was no RCD tripping

the order in which things happened and what parts you replaced and when can have a huge bearing. if the heater ntc was blowing the rcd then changing the panel before curing the heater may damage the panel = OK im sorry i just threw all the info into the post and it must be confusing…

Order of replacement parts and issues (hope this helps)

Part 1 Front NTC.

A few months ago the heater stopped working on the dryer. After google check there was two possible issues 1) NTC on front or 2) heater blown. After running engineer check it competed with two heat settings so assumed heater was working and front NTC must be faulty. Pulled NTC tested and was showing as 0 reading. Easy £11 ish part so new one replaced (a grey one different code at the

2971900300- i checked with company and they said this is fine

) so fitted and after reset the heater switch it worked fine for three months. Then the flash/pop happened.

Part 2 Main board.

When the flash/pop happened i opened up the front and found the scorch marks on the plastic and scorches on the board so the new board was ordered and replaced and at this point the RCD started to flip.

Part 3 Interference filter

I then found a video saying that the dryer flips the RCD when plugged in the then it can be two things 1) the interference filter or 2) the heater has blown. As the filter was the cheapest option i thought that would be easiest to try first. Ordered part and fitted (forgot to screw it to the unit) and no tripping and all seemed to be working fine! So put all back together (remembering to screw filter in place this time) and once plugged in it tripped the RCD. I opened the unit back up and just for a test i unscrewed the filter and plugged it back in and it worked. So i screwed the filter back on and RCD flipped!

Part 4 Heater and new NTC (white one)

At this point it checked all connections and all seemed fine. I removed the heater and noticed the black marks around the back of the heater and the NTC switch on heater. So new heater ordered, fitted and all other parts fitted and NO RCD flip after this so put it down to knock on effect of NTC/heater on the blink. I then tested on heat and no heat. I then ran the engineer test and still no heat at this point i was goig to scrap and put it down to a loss but saw this post and thoght it was worth running it past you before pushing it out on to the front path.

Everything works on the panel and all programs work, auro, timer etc but just no heat.

Pete
PS I appreciate you answering and any help and no worries if its a no goer and i should’ve done things different its all learing to me even with the cost 🙂

Yes I replaced the board as it went pop, had scorched the plastic and the unit wouldn’t turn on, at this point I had not thought, or should I say google, that the heater had any issues.

[Specialist01269]

Sorry that should have said heater not New, I don’t blame you for not realising that there was a fault with the heater. Unfortunately you’ve been a victim of what we often come across, there are multiple sites where your told that it will be X part that has gone but never how to test and confirm this with a multimeter. We try to guide people in basic multimeter tests so that they don’t waste money on unnecessary parts.

[GingaPete]

No worries, I wouldn’t blame you if you did say it TBH 😉 If I had found this place first I think the issue would have been sorted a hell of a lot sooner and with less parts!! As I say this bloody things like triggers broom of only fools and horses now!! Hahaaa

[Specialist01269]

Have you checked the new board for burn marks ?. Sadly the heater fault may well have killed the new PCB.

[GingaPete]

Board looks fine no marks and all lights up as you would expect and goes through all settings

[electrofix]

to be honesty if the board has gone it will be a small surface mount resistor so you may not see any burn marks

had a beko dryer with similar problems ie tripping RCD. Replaced heater with new and tripping stopped but still no heat. traced wired from heater NTC to board and traced tracks to find blown surface mount resistor (very small component can only see its blown with magnifying glass). replaced resistor and all was well
