Only joking with the spud, don't want to cash in my chips yet.I can test for voltage ,polarity and resistance . I will have to get a dedicated separate supply for the router and control hub for the central heating, and just hope for no power cuts as 2-3 days of phone calls is wearing and a...

Thanks John, could not get a voltage but certainly a good spark when crossed up. I plugged in my Makita charger and that seemed to drain off the problem.Have to be very carefull not to trip off the main RCD as it causes agro with the central heating remote access system.

Hi Sparky,i think it was a wire for the bell,but seem to remember that the bell box battery/cap took ages to die,so maybe did not get the right one!!. I have to take down a DT420 sensor to decorate ,how to disable the internal sounder?.

Could it be that the one really hot rad is taking most of the flow?, balance the system?,

I seem to have landed on another planet, no idea what you are talking about!!,the residual current is not 250v but as I have a pacemaker I have to be cautious. Can't turn off the supply to the other floors as causes days of problems with new heating system which will not re-boot without a whole...

Recently swapped my 40 ? year old Baxi (still working fine!) for a Worcester Combi in the loft and BG's system. Beginning to wish for my old system to come back!!. Seem to be talking to the Geek squad every week to keep it going. Have I bought a pup?, too much technology??.

Many years ago I rewired my own houses and fitted fuse boards etc,so not a complete noob, I have test gear , Working on fitting extra sockets with the ring unpowered I still get minor shocks and tripping out , what is the likely source ? the only thing left would seem to be a leak onto the earth...

Hi, I had this system installed about 20 years ago,with a remote keypad, the system works fine inside the house at present,some time ago the strobe overheated (got damp) and blew a fast blow fuse,at the time this fuse blowing also unpowered the keyboard so I pulled a wire off in the main board...

Hi zipper, Cant use that link. If i get it appart and need any more values i'll be in contact .thanks again.

Thanks Zipper, how do i PM you?, I have no problem testing stuff ,just can't see how to get it out without breaking, does the micro switch on the heater lever up and out? are the clips on the ntc on both sides? if so one is behind out of sight? ,the how to information would help possibly.

Thanks for the info Zipper, can't see PM adress for you on the site, must be getting more stupid daily!!, How to test resistance of thermostat from pcb plug? would machine need to be Running? I can do that, not running plug reads infinity, pressure switch stopping me ?.

Hi Zipper, Still working on the Dishwasher, The PCB has been off and checked out by QER, but no power to heater still, I would like to test the resistance of the thermostat on top of the heater 20-50 k ?? is it possible to test or get this off without big stripdown ? I have had the machine...

Thanks Zipper, think i will send off pcb for repair.

HI, water not heating, local engineer says no feed from PCB, He can replace but thinks it will need reprogramming which means a Bosch AGent, is this likely?, the cost of this will write off the machine, I'm thinking of removing relays to test , are they availiable? will reprogramming still be...

The knocking is comming from a device on the fill hose ,i did try adding a couple of litres but 1 hour later no heat. think i need to get the safety devices off the heater to check them any advice getting them off?,where is the thermostat, thanks mate.
