Re: Indesit W161 lamp flash codes
I’ll trace the heater wiring back to see which relay it is. Thanks.
Re: Indesit W161 lamp flash codes
Well I traced the heater wiring and it connects to pin2 of connector CNH. This doesn’t connect to a relay but various other edge connections on other connectors – so back off the board. It’s a bit of a nightmare. But all the relays on the board do work correctly and are not stuck. I wish I had a wiring diagram, but I bet those are rarer than hen’s teeth.
It seems that the heater is switched on the neutral? The blue wire from it – BL1, connects to the brown – BL2, on connector CN1 via relay RL1. Why are they mixing up the colours like that? Crazy! 😕Re: Indesit W161 lamp flash codes
Ok. All relays check out ok on the board. The driver for these is the uln2003a chip which is a darlington driver driven directly from the 6433642 cpu. They all c/o correctly when driven from the output side of the uln2003a. So it’s not the relay, and the heater and temp sensor check out ok too. The only thing left is possibly the edge connectors – I’ve cleaned these and reflowed them. If that doesn’t work then I have to assume that the eeprom program is corrupt? Unless anyone else has experience of this? Any comments welcome, thanks.
in fact, no.. ill just tell you what the manufacturers tech bulletin says
f-08 heater RELAY stuck
will that do?
Re: Indesit W161 lamp flash codes
Sorry about that, I’m only relating what I’ve found which is that the relay isn’t stuck. That’s why I did the last post. Thanks for the help, much appreciated.

Has it occurred to you that it “may” have been stuck at the time of “self-diagnosis” and subsequently unstuck before you tested it as OK ?
these are not “industrial” relays….points are likely to get very “splashy” as they burn-out…thus a generalised fault-code……you’d hardly expect the manufacturer to state…”relay knackered”, would you.?…for the cost of one, just listen to Helo. and put one in.
