Hi - does anyone know where I can get a replacement on/off switch for my Acer Aspire desktop pc? My "darling" grandson spilt coke over the front and now the switch has become very temperamental and sluggish! I have tried all sorts of switch cleaning fluids but it's time now to replace it...

Bought a new actuator today and fitted it - all seems to be working normally but I'm not crowing yet! I'll test it out over the weekend before I believe that the fault is fixed - and not - like some have told me - the boiler! Very Many thanks - particularly to D Hailsham for all the advice &...

Hi - valve moving quite freely - albeit witha total movement of about 20 degrees. Readings with orange disconnected and CH selected is 0v. This morning I needed to switch HW on to get the boiler to fire! Does this still point to the actuator - or a boiler fault?

Sorry! I should have said that I took these readings with the orange wire disconnected. I've just re done it & white & grey show 240v but orange is just about 10v. Do you think that it is the mechanical valve or the actuator that is at fault? Thanks for all your efforts but I'm thinking...

Checked as before - with system "normal" (Boiler & Pump On) all readings (White, Grey & Orange ) are 240v. When Boiler & Pump go Off (after about 20mins!) White & Grey are still 240v but Orange is 0v. You can hear the switch roll to the power off position. I've noticed that theOrange wire has a...

The voltages on white and grey with the switch in CH only position are both 240v but the orange connection (HW Call) is 0v. Does this mean the 3 way switch part is duff? It was only been fitted 9 months ago! Jock

I checked all the voltages at the 3 way valve with a multimeter as mentioned earlier - all were ok. Tried turning the boiler up to max & all trvs to max but makes no difference! When boiler is in sleep mode switching CH from programmer has no effect. Jock

No! Both HW & CH are showing "on" at the programmer but pump is stopped & boiler is on pilot. Jock

Hi, Water in header tank 1/4 full Water clean No water coming through tube when CH on. Thanks Jock

Not too sure! There are header tanks in the loft with cistern type ballcock valves if that helps.

Checked all voltages at system start - all fine and but now, 1 hour later everything stopped but voltages at 3 way valve still as per readings kindly supplied by D Hailsham. Boiler sitting with pilot lit but nothing happening - programmer showing HW & CH ON! Still have an inkling that the boiler...

Sorry all - should have mentioned that there is no room stat. Everything has been working fine until this past few weeks! Including the 3 way switch for HW and/or CH. Thanks Jock

Hi All, Having a bit of a problem with my CH system whereas it starts up as programmed at 6pm then is due to go off at 10pm - only problem is that after about 1-2 hours all rads go cold. The boiler switches back to pilot only and the circulating pump stops. After about another hour it'll all...

Hi All, I have just taken delivery of a Servis M6725 machine and have 2 questions which are confusing me befor eI install it! 1. The machine is cold fill only, although this was not detailed on the spec -does this detract from the energy rating and time to wash as it has to heat the water...

Adam, I have a multimeter (Old Avometer) and the wires in the switches are: Lower: Common (Red), 1 Way (Yellow), 2 Way (Blue) Upper: Common (Red), 1 Way (Yellow & Black), 2 Way (Blue & Red) The upper switch has 2 extra wires (Red & Black) which disappear into the upper reaches of the loft...
