Re: hotpoint fdw65a error codes

Thanks for the quick reply, yes I agree after my continious problems with a washing machine and now the dishwasher I won’t be buying another hotpoint made item again…..

I’m fairly capable with a test meter but unfamiliar with dishwashers. Would you have any figures I could check for on the various components and any useful pointers to help me identify what is wrong.

I assume the pressure switch is in the water supply pipe after the pump, do you know if it is a signal/no signal switch or a variable voltage return signal? and I assume I could just bypass circuit board and supply power directly to the pump to check it works.

Are the comments about the NTC relevant to my problem?

I think I have already done that, it is not as you state a Hotpoint made item, it is 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} Italian made Indesit, that is what is wrong. :rolls:

The pressure switch is not in the water supply, it is connected via a small hose to the sump and is a simple changeover switch. There is a flow meter in the water supply which can also fail and TBH does fail more than the pressure switch but should give 4+5 as an error code. There is also a device called a pressure sensor which is located in the hose from the main pump to the lower spray arm. 3+5 should come up after the machine has filled but as I and many others have said in the past, the fault codes are only a guide and when coupled with a machine with so many known faults it is a nightmare trying to sort them out. I would not advise bypassing anything in the way you suggest.

The tech info we have access to gives very little of any use regarding what you call ‘figures for various components’

You could become involved in what our Dear Leader calls ‘parts bingo’, if that is the option you want to go down then changing the flow meter would be the cheapest option to try next.

Re: hotpoint fdw65a error codes

I came home tonight and though I would give it one last try before doing anymore testing. It worked!!, I’ve now run it though 2 wash cycles without fault.

Hopefully it is now sorted, if not i’ll try the items you suggested and then get back if i need anymore advice.

Thank you ever so much for you help, Andy

Re: hotpoint fdw65a error codes

Hi – Its my first time on a forum and I’m over 60 so please bear with me. I have a Hotpoint FDW65A dishwasher S/N 80422 0384 which I bought about 3 years ago and had shipped over to Africa. We only sorted our house out last year andtried the dishwasher for the first time. Initial attempts unsuccessful so I took of the back to investigate and found a rust red “clag” in the salt resevoir which was probably a nest of some sort. I stripped it down and cleaned it and tried again. Everything seemed to work normally to start with but it never reached the pumping out stage after the main wash and when I openned the front the water was not hot. My assumption is that the heater has failed and so as it is not getting up to tempreature the pump out is not initiated so I plan to change the water heater. Does this sound sense and are there any other parts which might need to be changed as well?

Re: hotpoint fdw65a error codes

The pump should drain out at the very start of any programme before it even fills to wash, the heater has no effect on the drain pump at all.

If it has been stood for some years then it could be the drain pump that has seized or has a blockage. You may have disturbed the wiring to the pump when you ‘stripped it down’.

Although both the heaters and control electronics on these are very poor I would not advise changing the heater until it has been checked to see if it is actually faulty. A good multimeter or megger is required to test the heater for continuity, resistance and insulation before even thinking about changing it. 😉

The drain pump circuit is routed through the main circulation pump motor on some of these but as you say it did a wash action then that ‘should’ be OK.

Interested to know how you took the back off, it doesn’t have a removable back???

Is the dishwasher still in Africa as you ‘appear’ to be posting from the UK?

PS. I’m over 65, there are lots of people much younger than you who are totally clueless so don’t worry about your age. 8)

Re: hotpoint fdw65a error codes

Hi Young Jim – Thanks for your prompt response. IT’s hot over there and I laiod the machine on its side and took the base off but that looked like a back!

I can confirm that I cleaned out and checked the drain pump and that is working fine if I “jump” the programme onto the rinse cycle. As I say everything works up until it reaches the main wash cycle when it just hangs circulating the water and making the occasiona beep. That is when we stop it after a good while and oper the front to find it full of cold water. What actually triggers the start of the drin pump at the end of the wash cycle? How do I find out what reading I should get on the water heater to see if it is faulty? As I can get these in UK for around £25 I’d planned to take one over on spec.

Re: hotpoint fdw65a error codes

You should only lie the machine on its back or the left hand ( from front ) side. Lying it down on its right side can lead to water getting into places it shouldn’t.

When you set the machine to any programme, the drain pump should run for several seconds before it starts to fill for the wash.

If you do get this initial drain sequence then your drain pump is fine.

If you check for continuity and get an open circuit reading then the heater is faulty.

When you get the beep you should also get one or two of the lights on the front flashing an error message.

From your description it does sound as though you have a ‘no heat’ problem. If you can advance or reset the programme to get it to drain out the pump then and its circuits are OK.
The control PCB is just as likely to cause a ‘no heat’ fault on these, there are two different types used, both around £75. List price for the element is around £49.00 so £25 sounds a bit suss to me. 😉

Re: hotpoint fdw65a error codes

Luckily the layout of the kitchen meant that it was layed on its LHS – Phew! I’m happy that the drain pump is working fine so my plan remains to take out a replacement heater on spec to see if that sorts the problem. If not I’ll then get a new PCB when we are next in England. I note your comment re the price of the heater element an will be aware of imitations!

Many thanks for your help.

Re: hotpoint fdw65a error codes

At least you will have a spare element for future use. It is not that easy to change, some very awkward hose clips so testing it first is still the best advice.

Correct part number of heater is C00057684.
PCB is C00143209.
