immersion

maxamillius

immersion not heating water but not tripping breaker,any thoughts?
i am a sparks work in maintenance so have not done one in a long time,
thanks guys!

meercat

either the thermostat
or the overheat has tripped
or faulty timer
or faulty immersion switch
or burnt out connection
or blown fuse/tripswitch
or element gone(unlikely if nothing blown)

maxamillius

thanks for speedy reply meercat,tested switch continuity all good there,no overheat on the stat so cant be that either!i just find it strange that if it is the element why its not tripping the breaker!!

meercat

sometimes those overheat switches are un noticable
how old is the immersion
have you 230v to each element

maxamillius

doesnt look to old mate had a good look around for the overheat and could not see one anywhere,i know on my one at home its quite noticeable!

symptoms do seem to point to the overheat though any idea when they started putting them on the stat?

maxamillius

sorry ye 230 goin to each element aswell mate!

meercat

4-5 years on some makes
have you checked voltage to elements
you hardly have a clip on amp meter to check loads

meercat

any chance pic of stat

maxamillius

unfortunately i cant get one at the moment as im just home from the house!in between the 2 terminals it looks like there was an overheat but it wasnt raised much so im pretty certain thats not it!
no continuity through stat when immersion is off...correct?

if there is no hot water in cylinder then there should be continuity through the stat

maxamillius

tank water cold power off and no continuity through the stat!

Faulty Stat, stat should be closed

continuity is all well and good, but it's an ohmic value you want to see. At a guess you'd prob want to see about 40Ohms through the element.

18 ohms through the bath element, 26 through the sink. They are roughly what to expect.

Through the stat which is what was mentioned was missing should be 0 ohms.

No its something like 19 and 25 for the 3 and 2kw
