Water in fuse box.

Dear Mike,

Our PULSACOIL 2000 is a strange machine, it basically work most of the time, but once in a while there is no hot water in the morning, or when we come back from holiday. Now to get hot water I have to reset, and this is basically how I do it, there are 2 black boxes with a sort of fuse in it, and I have to stick my pen in, to push back the button. This immediately switches on the boiler and I have to wait for the water to heat up. So I have been wondering what the cause could be from the popping out of the fuse thingy? And I noticed that in the top fuse box, there is always a little bit of water in it when it switches off.

So now my question, what can I do about it and more importantly I think I need someone to fix this problem. Do you recognise this problem?

Thank you in advance

Kind regards,

Jochem

Are you referring to the fuses in the unit.
Or out side the unit?
Any water entering electrical components must be found and stopped.
You may have to switch the unit off ( if the water is in the fuse inside the unit) And see what happens when it cools down.
Not had this before.
Take some pictures and post on here.
It often helps a lot.

I meant the 3kW on-peak boost immersion thing. In the black cover there is always some moist/water when there is no hot water. So when I put a pen in the 'fuse' it start to heat up, but obviously this should not happen. Please see the photo

Thanks so far

No picture but we've got there!
You need to remove the stat and see if the stem is wet.
If it is the rod stat pocket in the immersion heater is leaking. ( New heater)
OR
It could be the stat is popping out (to hot)
Is it a genuine Gledhill stat?
You need to have the stats set at 72c
I don't think normal stats are up to being in thermal stores.
You can buy stats here
http://www.segel.co.uk/
But check the above first, as it may be the heater pocket leaking.
Check both heaters.
As in all case ensure the unit is switched off before working on it!
If in doubt, Google up Gledhill repairer for your area.
Look on home page this site, list of advertisers.
Or contact Gledhill who may give you contact of some one.

Hi Mike,

I will have a look when I get home.

Hope you will be able to see the picture, so it will explain my desciption.

Good picture.
Looks like the rod stat pocket IS leaking.
Just check it though.
Will need drain down and new heater and stat fitted.
And 1 litre of inhibitor added to the system.

Thanks Mike,

so basically I need a new immersion heater c/w stat 11 fitted? This will mean that I have to pre order this on internet at that shop you gave me a link for and have someone come and do it for me, right? As well as service it.

But to your opinion, the problem of the boiler switching off is the STAT, and by replacing it, it will not do that anymore?

Thank you again!
