We have a Hoover AL 130 which has developed a problem with the pressure switch.

It seems extraordinarily sensitive. Slightly too much soap, too much washing, r in the month, and it will click and click and click instead of switching off the water valve. It will then work right for a week or two before the problem surfaces again. It is driving my wife bonkers.

I have blown down the tube from the drum, which is clear and does not appear to be holed. On taking the switch off I find it has three adjustment screws. Looking from the back, with the hose connection uppermost, they are:- central, ten o clock, and there is a very deep one just below the hose connection. The one at ten o clock is half way out of its housing.

I cannot find an adjustment proceedure for these on the internet, and I cannot find a supplier or a new one. I have never in thirty years called a repair man in yet and am loath to do so now obver something I seem to have diagnosed correctly, but don't just like to 'twiddle a screw and see what happens' - especially as there are three to choose from!!

Anyone tell me how to adjust the thing, or where to get a new one if this isn't a good idea?

Thanks
