Re: Help an Aussie with a Hotpoint WD420
Hi Martin,
All new devices have a microcontroller on board that ‘step’ through a program at a certain frequency. This frequency is determined via the crystal.
Iadom, you wouldn’t believe how often I have wanted to do that!

Re: Help an Aussie with a Hotpoint WD420
Certainly am the same guy!
What a small world hey 😉
Yeah, have chased up a service rep in Melbourne that can supply the PCB at a reasonable cost. Would still love to figure out what the fault was / is though.
I am pretty confident it is the crystal on the controller but the part number makes no sense…..
6 Pin oscillator marked “491 E” if anyone is familiar!
I dropped a 4Mhz Resonator in with no success.
Might get the CRO onto the new board if it fixes the problem and report back, would be a cheap fix for the other guys out there with similar problems.
Best,
James
Re: Help an Aussie with a Hotpoint WD420
Thanks for the reply Penguin!
Anyone out their know how I can get my hands on an electronics board for my machine under warranty in Australia?
I am an electronics engineer so will probably have a look at a component level repair in the first instance…..
I am thinking crystal / resonator to the main micro as the pcb isn’t shock mounted and gets a lot of vibration. Also fits with the fault I experienced (ie machine stopped mid program).
Best,
James
