Diagnosing electric shower fault

Aug 05, 2019 Last reply: 6 years ago 3 Replies

Hello,



I have a Triton T80xr electric shower which has stopped supplying hot water. In other words, whenever I use it the water is cold. Before this, there was a bit of iffiness and sometimes when the dial was set to 6 the water would be very hot and I would turn it to 5 and then back up to 6 and it would be reasonably hot as required. The on light on the unit still comes on, so it is still getting power.



Does this sound like a faulty power selector (replaceable, part S12121003, available new)? I haven't had the front off yet but would be grateful for some advice on what to look for or test.



Many thanks!

The main element might be open circuit, or one of them if there is more than one. A pressure or temperature sensor might be faulty. Or there might be a fault on the control board. Or the flow valve. As well as the part you mention. Further testing would be a good idea before investing in a new part. Also checking no obstruction the water supply or kinking of the outlet hose (they can fray inside). I just found a troubleshooting guide although it does not include running cold, just your "too hot" symptoms.

Generally, it is not worth repairing cheap electric showers. They are ~£80 new, far easier to just replace it, than repalce a part that may or may not be faulty.

might be the switch, might be some connection inside. Only way to find out is open it, with power off of course.
