A power shower has a pump that boosts the water from your hot water cylinder and your cold water tank. When it stops working, the cause is often simple. Try these checks first. Never open the shower cover: there is mains electricity inside.
1. Check the power
Is the pull cord or wall switch for the shower on? Has the trip switch (RCBO) for the shower dropped in your fuse board? If it trips again as soon as you reset it, leave it off.
2. Check the water
Run the hot and cold taps at the bathroom sink. If either is weak or does not run, the problem is the water supply, not the shower. Check that the cold water tank in the attic has water in it, and that the isolation valve on the pipe to the shower is open.
3. Clean the shower head
Limescale blocks the small holes in the shower head and makes the flow weak. Unscrew the head, soak it in descaler or vinegar, then rinse it.
4. Listen to the pump
If the pump runs but little water comes out, there may be an airlock. The troubleshooting page shows how to clear one. If the pump does not run at all, or makes a grinding noise, it needs a repair.
