Candy Tumble Dryer not heating

Model: Candy Grand O, GOC 1379 XB

Hello,
my tumble dryer has stopped heating up. My wife has noticed that its been less efficient for a few months but i didn’t do anything about (until it stopped and gave an error code E08). I’ve had a look on the forums and this relates to the thermal fuse.
So first of all i checked the filter in the condensing unit. It was completely blocked up with fluff. So i cleaned this all out, replaced it and off we went. I ran it for 20 minutes, empty, without an error code. In fact i didn’t check to see if it had heated up at this stage.

So the next day my wife done a wash as usual, put it in the tumble dryer and got the E08 error message after 10 minutes or so.

So then i read up a bit on the details and started to check the components. So far, here’s the report:
1. front NCT sensor – working fine
2. rear thermostat – showing continuity
3. rear thermal fuse – showing continuity, and cuts out under a flame, but regains continuity shortly after
4. heating element has 2 elements – 50 and 49.5 ohms on each.

I thought maybe it was the internal NCT sensor, so i ran it empty on a timed cycle (as opposed to the automatic one). Still no heat, just lots of cool air blowing out.

The dryer is now on a bench where i have access to all sides, so at each test i can easily check to see if there has been any heat. None so far.

Any advice would be greatly appreciated,

thanks, Shaun.

Re: Candy Tumble Dryer not heating

i would recheck the rear stats. on the candy if the overheat stat trips it will not reset and you have to change the element

Re: Candy Tumble Dryer not heating

There are 2 stats 1 on the heater 1 on the front plus 2 ntcs 1 on the heater and 1 on the front should have continuity through the 2 stats 0.5ohms and 0.5ohms on the rear ntc as well the front ntc is common to go on these thou, hope this advises you where to look

Thanks for that, Dave. Was thinking i should re-check them. In fact, when i checked the stats & heater element, I wasn’t 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} sure with the reading so i took it into the engineering department at work. And it was there that one of the electricians had a lighter under it before i had time to say ‘one shot fuse’. Saying that, it did regain continuity shortly after when it cooled down.

When you say to change the element, are you talking about just the overheat stat or the whole heating system (heater + 2 stats?)

OK, Dave, just took off the back cover and disconnected the heater. Re-checked the two heating elements and the stats – all OK.

After I also took out the condensor, poured a glass of water into the back reservoir to check if the sensor and water pump were all OK. As soon as i turned it on, no heat but the water was pumped into the main reservoir.

The only sensor i haven’t checked is the internal NCT one. I’d really like to avoid this if possible as it’s a good bit of dismantling, etc.

Any other ideas? Please?

Re: Candy Tumble Dryer not heating

To check the front ntc you will have to remove lid fascia panel (control panel) remove door and front panel and its on the bottom left corner like I said in previous post most likely problem.

Re: Candy Tumble Dryer not heating

Hello. For now i have checked the front NTC sensor as you’ve described. Its OK. But haven’t checked the second one inside the machine, below the drum. Do you think if this has gone it will stop the heater from working?

Does a NTC sensor prevent the heater from working?

Hello,

i have a problem with my tumble dryer that it is not heating. To avoid the long story in my other post, here’s the short version.

All thermostats, heater and NTC sensors are tested and working correctly, EXCEPT the NTC sensor located inside the machine, i assume measuring the temperature of the air leaving the condensor. If this isn’t working, will it prevent the heater working?

Thanks for any tips before i have to dismantle the whole machine.

Shaun.

Its so much easier if you stick to one problem, one thread. Spreading it about only leads to confusion. I assume you’re referring to your errant Candy dryer? You were given expert advice there, and yes the front NTC very likely IS the reason it won’t heat.

😡 :rolls:

Hi Martin,

thanks for getting back to me. As you said, i was given expert advice which i duely took on board and spent a good bit of time last night re-testing the stats as advised. But nothing new to report, only narrowing down the possible options.

however, as you can see from the thread above, the front NTC sensor is tested and OK. Its the NTC sensor inside the machine that i haven’t tested yet. As i said above, i assume this measuring outgoing air. However, if i use a timed cycle as opposed to an automatic one, would this sensor still be used?

sadly i don’t know how to add the wee faces, but if there was one saying ‘i’m not trying to mess you about, i’m just trying to get it fixed before my missus finally cracks up with me’, consider it added.

thank you – that’ll avoid any unnecessary hassle.

Re: Candy Tumble Dryer not heating

OK, just tested final (internal) NTC sensor. Its fine. In fact its the same model as the front one, so took both off to compare. Both giving exactly the same readings, about 20Kohms in the palm of the hand.
So if all 4 heating sensors are OK (2 NTC, 1 thermostat & 1 thermal fuse), heating element is OK, drum turns fine, air blowing fine, water pumping OK… anybody got any ideas why its not heating?

Re: Candy Tumble Dryer not heating

Ok the pcb has relays on it which brings the heater on so if your convinced that the heater which includes the stat and ntc are ok and the front 1are all ok the pcb will be faulty

Re: Candy Tumble Dryer not heating

ha ha, you read my mind – just ordered a new pcb (from whitegoods) about 20 minutes ago. Will see if this does the trick!
