Servis MK41 All Fabric Top Loader
Hi Guys
The "Mains" on does refer to the power indicator for the machine, I believe this is lit when the selector dial is pulled to start.
The early model MK41 had the black servis agitator like the twinnies, ( and earlier t/l MK22, MK38 ) then Servis introduced the grey Hi-Zone Power Agitator. Non of the UK guys have seen or have one of these machines, YET!!!
My Great Aunt had the previous version, which I remember aged 8, with the black agi, this had a soap dispenser top left of the washtub, pre-wash, main & conditioner.This model also had smaller dials instead of the rocker switches. All of the Servis models have 210s wide sweep with 65 osc per minute.
There is a twinny repairman in Walsall, Midlands, his main engineer used to work at the Servis factory all his life, he told me the story of when this machine was sent to Australia they had a call to say one of the machines had totally exploded in use and had taken out the room and porch area of the house it was in...This was a new model so Servis UK sent an engineer over to see if he could identify the problem, fearing a mega problem with the build. The machine was indeed in tatters & bits along with the room etc..
Turns out after a lot of searching that the owner had very dirty oily clothes and had washed them with some sort of dry-cleaner solvent, fumes had built up, a spark from the timer and ...BANG!!!
