Hotpoint wd440 eprom setup

[snig]

Fitted a new module and eprom today but getting F09 code showing. eprom/ setup fault. Have double checked connection but can see nothing wrong. Any ideas. Original board blew due to suppresser short.

you did buy a programmed eprom, didnt you?

Re: Hotpoint wd440 eprom setup

Yes, this model has several eprom options, this one is cold fill only and therefore available, but some i see were no longer available and you had to buy a blank one and programme it.( VERY helpful )I had advised the customer to use his 5 year warranty but he wanted me to do it. I’m beginning to wish he hadn’t. Has anyone got a wiring /connection diagram for mark 4 board just in case i’ve reversed a connection.(they are not all keyed. some are single amp tags and we all no it can happen to the best of us)

id be surprised if wiring it up wrong would cause an eprom set up error tbh

its usually the eprom

Re: Hotpoint wd440 eprom setup

For this model there is at least 3 eproms depending on which dryer version you have. (there are 3) then if it is cold fill or hot/cold fill. 🙁

On some the colour of the label on the motor can make a different to. 👿 😥

Re: Hotpoint wd440 eprom setup

Hi this is my first post, been doing a lot of reading, whenever i get a hopint indesit, which is a lot of the time!
And has a board fault i always use emw and px the old board they come with a year’s g/tee and pre programmed so just plug them in no aggro and helps keep the repair cost down, whenever i take any boards off i use a marker pen and mark up so i don’t forget how it was,

Hope is of help for other jobs like this,

Finally resolved problem which was incorrect eeprom. this one is for new heater box design, i didn’t realise there were so many options. Thanks for the advise.
Although still unsure what the difference is between heater boxes should i be unlucky enough to come across another one?

the three in circulation are

original – machine was hot and cold fill , had a 4 way valve, and had a flushing valve with a filter at the back of the box

second wave – hold and cold valve, 4th valve and filter removed – heater box reverted to merloni spiral element and in line thermal fuse

3rd revision – cold fill only , flushing valve was re introduced

the bit you need to look for is whether it is h+c fill, or just cold fill and if it has a 4 way/3 way valve and a filter at the back of the box

does my head in, remove it – re introduce it, remove it – reintroduce it

none of em work well anyway

does this clarify anything?
