Tribune Premier TP180e blowing fuses

[galaxy_plumbing]

Hi guys,

went to this water heater today. It started blowing fuses. I tested both elements for short circuit and found that top one had short circuit between live and neutral. I managed to get new element from merchant. After all the hassle when I try to remove old one I was happy to install new element, tested for leaks, connected wires, put new fuse in the spur, switched it on and it went through new element again, so not sure why that happened. I tested all connections for both elements and thermostats and haven't found any more short circuits. I disconnected top element , replaced fuse and it blown again. So my suspicious is either the bottom element or thermostat is maybe faulty as there is nothing else connected to it except the programmer on the wall next to cylinder.

Could any of you give me some hints what else could be wrong. I really want to fix it as this could lead to more work for me.

Cheers guys,

abedy

Take the programmer out of the circuit and give it a try.

Elimination, disconnect bottom and top elements. Try again, if it blows fuses its the timer.

Faster fingers than me. Same results different process.

Also don't forget the important rule. Just cos it's new out the box doesn't mean it's not knackered.

I will just disconnect everything and start connecting elements back one by one. You right Simon, only Pink Panther knows for how that element was laying on the shelf.

Ok, managed to get an electrician for tomorrow while I'm there. That will save lots of hassle

Problem discovered. Bottom element has short circuit to earth. Will need replacing.
