Our ISE 1606W only powers the heater element occasionally (I’ve already mistakenly replaced the element but the resistance is good 25 ohms). So selecting 95 degrees C wash we sometimes get the glass front warm (and 240 v is seen across the heater element) but often it remains cold (using the same settings). All the wash cycles work normally apart from the lack of heating – the wash quality is not great.
I’ve measured the resistance across the thermistor and it varies from about 14.5K ohms at room temperature to 2.3K ohms at 60 degrees C. This is in a higher resistance range than I’ve seen on youtube (cold 6k, hot 1.2K) but I assume they vary by model.
The ISE also has a strange connector for the thermistor – does it actually connect into the water (I did get a bit of water out when I removed it and I’m surprised the connector design doesn’t leak!) or does it work by conduction?
Any thoughts please – should I change the thermistor?
DavidRe: ISE 1606W not heating the water
I can explain it but, you may not like the answer in a way…
The thermistor is not exposed to water at all and never should be. If it is, the resistance will be wrong and all manners of mad things can happen.
If the machine is overloaded it will leak through the back of the soap drawer, run round the tank and onto the thermistor. Very common to happen.
Too much detergent can have the same effect in two ways, excessive water released from laundry on spin and all the more if coupled with overloading and/or the dispenser doesn’t clear fast enough and, leaks out the drawer again and runs onto the thermistor.
Usually if you let it dry out then take account of the above and it’ll be fine.
And, hence the intermittent nature or results.
If the machine doesn’t heat at all it’ll error out. You will not feel heat in the glass on most programs.

Re: ISE 1606W not heating the water
Ok that seems to be it ,thanks
There is mild corrosion around the bottom front of the soap tray, around the thermistor connection hole and also on the base plate of the machine. I dried everything off and cleaned the soap tray and checked that the soap tray drain tube wasn’t blocked (flexible along the tube).Tried the washer again several times and found a small puddle on the base plate. Then I noticed that there is a seepage from where the soap drain tube connects into the drum – the outside of the drum is wet and this is in line to get into the thermistor housing. Seen someone suggest that there might be clothing blocking the outlet but don’t see how that could get between the drums with as ISE.
Is this gasket leak (economically) repairable?
Thanks
DavidRe: ISE 1606W not heating the water
There won’t be clothing in there.
Built up soap residues maybe and more than likely it’s been happening for years and it’s just caused an issue as, it’s 99.9999{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} down to use.
I’d try running a maintenance wash first, see if that clears it out. After than try sealing the hose but, if the soap and load levels are right or below where they ought to be, it won’t or shouldn’t leak from there.

Re: ISE 1606W not heating the water
I’ve tried plenty of maintenance washes – obvious issue is that the water doesn’t heat often since the thermistor is mostly wet.
You suggested sealing the hose inlet into the drum – can this be done after thorough cleaning with e.g. silicone sealant or does the joint need to be remade from the inside which I assume would need the drum disassembled.
So can this be fixed diy, do I need an engineer or will this be too expensive to fix
Thanks
DavidRe: ISE 1606W not heating the water
You can seal yes, just using silicone sealant or debor but, if the cause isn’t resolved it will leak again eventually.
In every one I’ve looked at it’s been the detergent, the quantity of detergent or just overloading that’s caused it. There’s really nothing else that can.

Re: ISE 1606W not heating the water
Just to throw a little confusion into the diagnosis I have found two of these one of which is my own where the heater had failed and the machines did not error out but completed the wash without heating.
Amazing really how well they wash in cold water but after a while start to smell a bit.Steve
Re: ISE 1606W not heating the water
Just as a follow up – completely removed the hose into the drum, cleaned it up with acetone and glued back in with debor (product sheet for debor says it contains acetone so I reckoned acetone safe as a cleaner)
Waited 36 hours and tested – no leaks! Also ran some cleaning tablets.
Dried out thermistor and now the 95 degree wash reliably heats the glass. Not sure about the 60 degree wash but assume is ok.
Really surprised (disappointed) that there is no flood detection on the ISE since the bottom plate is quite corroded – must have had the problem quite a while and a musty room too!
Thanks for all the help on thisRe: ISE 1606W not heating the water
David, I’d bet that this is what’s happening but, internally…

If you don’t solve the actual cause of the leak then the water will go somewhere else ultimately. Or cause another issue possibly.
What you describe, the rusty base, leak from the hose/s are classic overloading and overdosing symptoms and, I do mean classic to the point I can almost 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} guarantee that’s the real problem and, has been for a long time.
Feel free to ignore it but don’t be surprised if it comes back to haunt later.
