Electric Shower Problems: Five most common faults (and what causes them)

shower doctorHere at The Shower Doctor, every day we receive emails and phone calls from people that have faults with their electric shower, so what we are about to do here is run through the top 5 faults with electric showers and give you some idea of where to look to find where the problem is with the shower.

  • The water is tepid, or there is not enough power
    The reason that the shower is tepid, or there is not enough power from it, is perhaps because of the micro switch. This may have burnt out inside and not be allowing the power through to the elements. Indeed, it could be an element itself, if one of the elements has burnt out then the shower will only be working at half power.
  • My shower is going hot & cold
    If your shower is going hot and cold, it’s usually caused by not enough water getting to the shower. So first of all check that the valve coming into your house is fully open and the valve in line with the shower is fully open. If they are both fully open, then it could be a problem with your showers flow valve, that actually comes into the shower. If this is the case, they will need replacing.
  • My shower is absolutely cold
    If your shower is absolutely cold, what could be causing it is the Thermal Cut-Out (TCO) and what happens is if the shower overheats, it cuts off the power to the elements. If the shower overheats just a little, it cuts it off and resets. If this keeps happening, or indeed the shower gets far too hot and it cuts out completely, this will need replacing.
  • There is water coming from the bottom of my shower
    If you find that there is water coming from the bottom of your shower, it may be that the PRD has activated (Pressure Relief Device). All of the manufacturers have them and they are slightly different as to how they do them. Mostly, it’s a ball inside that gets ejected when the pressure builds up inside the heating tank. What normally causes this is a blocked shower head, or the hose is kinked.
  • There is no water coming from the shower at all (or it stops and starts)
    This is it, the number one fault with electric showers. The solenoid valve. If you find the shower stops working completely, or cuts off (particularly when you have soap in your hair) this is the culprit. It’s usually this part, the coil and the coil breaks down. The coil (when working) lifts a plunger inside the solenoid valve and allows the water into the shower. When the coil breaks down, the water stops running and that’s what causes the problem.
