Hotpoint wm22

Excellent. Another one of these great machines saved from the tip. I cant tell you much as i had the WM64/wm62, the last ever descent built hotpoint before things went downhill with the hotpoint wma series etc..
 
WM22A

Having used a Hotpoint 9536 Washer for years when i lived at home i knew every part of the programming of that machine, so i tried it out last night on a cotton programme. This Washer is very similar to the 9536 the same good old timer noises, apart from a few great features the first being being the 2 spin bursts in between the rinses. The 9536 used to do 2 short 500rpm spin bursts which i found disappointing the WM22 does a slightly longer 500rpm burst but then to my surprise a full speed 1000rpm spin burst which i was not expecting to happen also when it's heating on the cottons cycles the drum speed is short & gentle just the same as on the wool cycle. The out of balance control is not as fussy like on todays machines but it still kicks in but only if the load is seriously un-balanced.

Module

It has a detachable speed control circuit board attached to the back of the timer, this timer is from the earlier WM22 series. The timer was changed to a one piece set up some time later.
 
Thanks for the photo

Your machine must be a crossover machine, making it a rarity as it's unusual for a for a WM-series machine to have the pre August 1995 electronics coupled with the post August 1995 fascia & dial.

Timer

Well James i wasn't expecting to see this older style timer in this machine but i do much prefer it. (ie the spinning profile better than the 95 series models) So yes i guess mine is one of the first early WM models before the timer changed to the microprocessor controlled machines. I looked through the instruction manual last night & it says that this machine should do a couple of ant-crease tumbles after the final spin but it doesn't, so maybe it was just Hotpoint using up the last of the old style timers with a few modifications added.

It seems odd that a machine that new had a mechanical timer.

When were the last machines made which used a mechanical timer like this before they went fully electronic?
 
Electronic machines...

Started to appear in the late 70's/early 80's from Servis & Hotpoint. Hoover catching up sometime around the mid 80's. They were expensive but the electronics were reliable. To make electronic control available to the nation, hybrid timers where made, this is where the cams on the timer select "files" or processes for the microprocesser to carry out. Servis were the first to use hybrid electronics followed by Hoover and their New Wave in the early 90's. Hotpoint started to use them in 1995 phasing out mechanical timers.
