We in the trade are faced many times with dilemma’s just like this I’m afraid. Plug a new one in will likely fix the problem, but which one? or maybe both are at fault? How much do you want to throw into sorting this problem?

All I can say is that a duff Hoover AC180 is better than a brand new Hoover. (which tells you something about modern Hoover’s I guess?)

Re: washer over fill

well, I phoned the company that I spoke of before who I saw on the internet and I sent a photo of my board and they have never seen one before. It was retrofitted about 5 years or so after I bought the machine because I had a repair insurance policy and the engineer came out and replace the mechanical programme set up with an array of lights and a led display and the board to go with it. The internet company forwarded me to an extremely helpful electronics company and I had a chat with the guy there and he will look at my board and repair it if possible. However, I went back to my machine and to my shame the clicking is not actually coming from the board, as I said earlier, but from the pressure switch. The situatiopn now is that tomorrow morning I will go to GIAS (don’t know where else to go to) get and fit a pressure switch. I have sent a photo to the helpful electronics engineer that I spoke to. If the pressure switch fixes the problem then I have clean socks if it doesn’t then I will send my board to the Re-lectronics guy and take it from there. Basically I am seriously broke and I need clean clothes (occasionally).

Re: washer over fill

I wonder if you have checked the air pressure hose for leaks? Simply blow gently up the pipe (air chamber end) until the Pressure switch clicks, then hold the end of the pipe tightly with a pair of pliers and wait a few seconds to see is the Pressure switch clicks out caused by a pin-hole in that hose?

I’ve never changed a Pressure switch on that model before by the way!

I wonder what the state of the Heating Elements insulation is like also? 😕

Re: washer over fill

I have had one, and only one New Wave machine on which the pressure switch was causing the fill to fire on and off rapidly. It was a conventional timer model though.

Hi, I checked the pressure tubes last night by taking each of the off, holding my thumb over one end and blowing hard into the other end. I did think about putting them into a bowl of water, similar to an innertube but i just held the pressure, didn’t notice any difference and passed them. however, since that time, and since I can’t do anything until tomorrow I put my sodden wash onto a “4” wash (everything I own goes into a “5” wash) and it seems to be running without a problem. As soon as it finishes I will run the pin hole check. Also if I can work out which terminals I need then I should be able to get a continuity across two of them whilst blowing down the tube to tell me that it is ok. It doesn’t look that difficult to change. 7 wires (I’ve already labelled them) and a push spring gripper thing on the back to hold it onto a slot in the side panel.

I did think of doing a boil wash to check the heater.

Re: washer over fill

I fitted a new pressure switch about an hour ago, set a “5” wash going and so far it is looking good.

Deep joy! and I’m pleased your persistence paid off, it certainly proved me wrong about AC180 Pressure Switches that’s for sure 😳

The one I had threw me as well, in fact I think I posted here about the fault at the time, initially suspecting the valves, or the timer. Thankfully I only tried the valves before deciding to try the pressure switch. 🙂

Re: washer over fill

The pressure switch on a washer rarely is faulty!

You must be kinda unlucky, but have clean socks now 😀

Re: washer over fill

Thanks ever so much for all your help. I can get back on with my life now! 2 things that nearly had me going off in the wrong direction:
1. When I reassembled the machine, after I had had the front off and the water was coming in “like a machine gun”, when I took it apart again I noticed that the white plastic clamp around the tubing between the pressure switch and the door interlock had not been put back on (by me). I wondered whether that had caused a pressure leak that caused the strange demand for water.
2. When I turned the machine on and when I selected a program it would spend ages clicking. I was convinced (late at night in a cold, damp cellar) that the clicking was coming from the pcb area. I put my ear to the pressure sw etc and still it did not seem to be coming from it.

Also, interestingly, it worked absolutely fine on a 4 wash last night and after the 4 wash I did a fast spin on a 10 wash.

Fingers crossed for the next few days.
