Indesit Iwde126 Overheating
Hi,
My washer/dryer (Indesit IWDE126) overheated last Friday night - was on a 40 degree wash and just started steaming. I turned it off pretty quickly, but it had got pretty hot (I couldn't handle the clothes).
It now starts ok, but stops mid-cycle with the 2 right-hand most lights (extra rinse and spin selector) flashing.
Where do I start bug chasing?
Thanks, James
[ I've seen something saying that these lights add up to error code 3 =relates to the NTC the water temperature sensor, check the connections and replace if required. Does that sound right?]
(I've checked the coin catcher, empty;
there doesn't seem to be any lint catcher to clear;
I've run it with the outlet into a bucket to check that was free flowing;
seems to run to completion with a cold wash;
tried the dryer for 15mins last night without problems...)

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Indesit IWDE126 overheating on heated washes, likely temperature sensing/control fault
- The problem
- Indesit IWDE126 washer/dryer overheated during a 40°C wash and produced steam, with clothes becoming too hot to handle. Afterwards it would start normally but stop mid-cycle with the two right-hand lights flashing. The machine would complete a cold wash, and the dryer reportedly ran for 15 minutes without issue.
- Likely cause
- Most strongly supported diagnosis was a heating control fault involving the NTC thermistor, its wiring/connections, or the main PCB. The accepted reply said overheating is often caused by the heating element thermostat/NTC, the main PCB, or a connection fault between them. The thermistor reading reported by the owner suggested it was responding to temperature, so the exact failed part was not confirmed.
- What fixed it
- Recommended action was to check for a loose connection on the NTC and test the thermistor. After the owner found the thermistor appeared to change resistance with warmth and saw no obvious PCB damage, no further DIY checks were advised. Further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Coin catcher checked and found empty
- Outlet run into a bucket and found free flowing
- Machine completed a cold wash
- Dryer ran for 15 minutes without problems
- Thermistor measured about 24 kΩ, dropping to about 12 kΩ in warm water
- Visual check of wiring and PCB found no obvious damage or water ingress
- Parts or tools mentioned
- NTC thermistor
- Main PCB
- Multimeter/continuity test meter
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello, none of the things you checked would cause overheating. Overheating is often caused by a fault on the heating element's thermostat (usually an NTC thermistor these days) or main pcb or a connection fault between them. Carefully check to see if there's a loose connection on the NTC and try to see if you can get any readings on it with a continuity test meter. If you can't see anything I'd get an engineer.

Hi, I've finally had the time to pull out the machine and get a multimeter onto the thermistor - it reads ~24 (kohms?) Which drops to about 12 in warmish water). Looks like the thermistor is OK?
I'm struggling to get the continuity meter onto the wiring but it all looks OK. PCB (assuming it is the unit at the back rear where the wiring harness runs to) has no obvious damage or water ingress.
Anything else to try?
Should I go to Indesit directly or can you recommend someone in Bristol?
Many Thanks,
James
In theory, if the thermistor was faulty the software running the wash cycle should abort the program with an error code so modern washing machine's should never over heat. However, anomalies and bad design can mean some faults are not detected by the software plus of course if the problem lies with the main PCB that contains the software it may also fail to defect a fault. I wouldn't try anything else, you've checked the basics which is all I recommend. You might be able to find a local repairman from my affiliates but if not Indesit usually do fixed repairs or have a 5 year parts guarantee although they'll usually charge around £100 labour.
