Re: Hotpoint Aquarius DWF35 not heating
Update:
Upon closer examination, there is a widened tooth on 1 gear and a corresponding wider gap to receive it on the other, so it is possible, tho awkward to realign these 2 parts. When I took another look at the PCB I noticed that the hole that takes one leg of the relay was very damaged. So I have soldered a “thickish” wire directly to the relay leg and connected to a suitabe part of the PCB. Seem to have done the job for the time being. Half a dozen washes without any problems!
Re: Hotpoint Aquarius DWF35 not heating
Just in case anyone can help……
I took the heater assy out, it was quite gunged up, I’ve cleaned it but I also made the mistake of removing the motor that drives a valve selecting the flow into the heater unit. I need to get the motor back on, but have lost the orientation. One half has a gear that operates a micro switch via a profiled outer circumference. The other half is a circucular plate that has holes to select which of the 2 inputs are open or closed. If anyone knows how to align these 2 bits …….
Well if not, it was for the tip anywayCheers. Andy
Re: Hotpoint Aquarius DWF35 not heating
Thanks, I think the heater element is OK, I wonder if somethink is preventing the switch from always working – might have one more look over the weekend …..
Re: Hotpoint Aquarius DWF35 not heating
Well after 2 sucessfull washes, the 3rd one failed to heat, so back to square 1. Anyone have any ideas what might cause an intermittent heat related issue? There is a switch above the heater element which I assume needs to be made for the heater to work. I have checked this and it appears to work when manually operated, but hard to test in situ. Any ideas welcome before a visit to the scrap heap (sorry re-cycling centre).
Cheers AndyRe: Hotpoint Aquarius DWF35 not heating
Its hard to say, the leg that is bad is the one that connects to the heater itself (i.e. not the 5V coil connections). The board is now looking a bit burnt at this point and the leg of the relay has lost its coating so wont solder properly. Anyway the good news is that I’ve found what appears to be a compatable relay from Maplin and put that in last night. It worked ok (a one off wash was good), but I will wait for a week or so until I get too excited. Thanks Andy
Re: DWF 35 How to find heater element?
Examined PCB a bit more closely and did discover a dry looking joint. Resolder all the relay connections and now I believe it is heating. Will post back if definitely fixed after a complete wash. Many thanks iadom for your help.
Re: DWF 35 How to find heater element?
Many thanks for the reply iadom.
Assuming the terminals to be located within an oval piece of white plastic towards the back of the machine? (viewed from RHS as suggested). If so then it would seem ok as resistance was 22 ohms.
Is the main PCB the one located on the front of the machine, that contains the switches and display? If so I’ve taken a look at it, nothing obviously burnt but 3 or 4 relays I think on it. Numbers I can see printed on the plastic surroundings:

The machine does wash OK, the heater does work, I just think it hadn’t heated up at the point the machine stopped?
Re: ISE Washing m/c pauses every wash
Just noticed your signature Martin, off to see The Best Exotic Marigold Hotel tonight!
Re: ISE Washing m/c pauses every wash
Model number is CI 555 WH
The problem seems to be consistent on the “quick” 40 degree cotton wash
Fills/heats/washes (about 45 mins?)
Fills and then stopsPress start (sometimes there is a tiny extra fill, less than a second) and then it carries on. I dont believe it has heated the water on the second fill.
IS there a weight sensor? I guess the washing weighs a lot more on the second fill?
