Hot water went off a couple of weeks ago, new stat fitted. Hot water back.


Hot water gone off again, just changed element - not working!!

checked with meter, element has 19 ohms (which is good for a 3kw so I've found) The old element is also the same.

240v through the stat to the post with the brown wire attached.

no heat though


any ideas?

Check tightness of connections to all terminals + check u have 240 @ live + neutral @ element still
Element ccould have gono now. Bud

I dont think so, the neutral is connected directly to the element, the live goes straight to the stat, then from the stat to the other post of the element.

disconect the wires to the immersion poles and check if you have Continuity from either live or neutral to earth if so get a new immersion i've seen new ones do this but not blow fuse/rcd

It's the stat, I was measuring wrong there's no voltage from the other side of the stat.

Why would the stat only last 2 weeks??

Holy jesus!! There's a bloody trip switch on it!!!


Just took the old stat apart and found it has a trip switch built in


Now, why would it trip? overheating??

How old cylinder or element
Do you live in a hard water area
element could be 'caled up' causing it to overheat + trip

hey up mate if the actuall body of the immersion has corroded it will keep tripping,
ive had it before a few times, ive changed a few where it has corroded and kept blowing the heater

worth a try bud

Cheers guys,

fitted a new element today, the old one looked old but not too badly scaled.

Hopefully that will be it [touches wood]

if its a new imerssion , i would say a faulty stat they can be quite sensative , i`ve had a few omerssions lately with faulty stats, there very sensative these new stats, is it a grey one with a black arrow for adjusting the temp, if so take stat back to merchants ...

i usually try get the red ring stats usually alot better
