Indesit/Ariston modules… Can they be replaced

Re: Indesit/Ariston modules… Can they be replaced

Don’t get this one Bob – you must know that there are hoardes of boards and eeproms to mix and match to your hearts content as outlined by the most excellent Fastrack technical disc……..

Yeah, some eeproms are soldered, some are on carriers – what’s the problem? If you give EMW the model number, you can even get a ready to go replacement for rather less dosh.

Or do we have a little outbreak of irony here? 😀

Re: Indesit/Ariston modules… Can they be replaced

Anyone who has ignored the plethora of Indesit/Ariston electronics problems over the years finds the flow of failures hasn’t deminished. In fact on the contrary, they are on the increase thanks to all the later series Hotpoint machines brandishing the same control gear!

So to assist Bob and many others, I have taken the liberty of reproducing the excellent technical notes of a leading company (thanks Tony of EMW 😉 ) in the repair and servicing of Indesit/Ariston and Hotpoint modules : –

“Are you one of those engineers who refuses to go near another Indesit W101, WI101, A1435 etc? In these days of low washing machine prices giving rise to fewer repairs you cannot afford to ignore this huge section of the market. Everybody knows about the dreaded ‘rotating timer’ whenever one of these machines goes into fault mode. But are they really beyond repair? NO! First thing to check is for blown tracks on the board. These are normally caused by shorting interlocks or pumps (normally around the terminals marked “CNF”. If the board has no burnt tracks then scrub the green side with a dry toothbrush, tighten each and every pin in the edge connectors by removing them, squeezing them with your fingers then refitting.

Now try the machine again. If it aborts straight away (before any wash action) then check the Thermistor (near the heater, about 25-40K pull both wires off first). The second thermistor (on washer-dryers) is on top of the drum (same value – often go open circuit or cable breaks inside the sleeving). Check heater for open/short circuit. If after all this it still aborts, replace the main board. If however the machine washes for a while before aborting, then change the CARBON BRUSHES (even though they may more than 90{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} left!) and the PRESSURE SWITCH (yes these burn inside causing random aborts after washing for a while) Do not replace with secondhand from a similar machine as it is also likely to be burnt. I know it is rare to change a Pressure Switch these days but these machines EAT THEM UP!!! Merely blowing up the switch and testing for continuity will reveal nothing. These switches only fail under load (when the heater is on). It is a good idea to carry the two types of Pressure Switch if you intend to repair these machines on a regular basis.”

The above information should help anyone to successfully repair these machines and to approach them with some confidence. I hope it helps dispell some of the myths surrounding them and the ‘rotating timer’ will be regarded not so much a challenge but rather a much needed extra source of income to those who dare venture…… 8)

i do those lots the dreaded 8 flasher nmachine will fill stop then fuill again but if relay is faulty then it will flash after the fist fill fitted loads always success
