to the shower unit and it is not making a noise
there is power to the transformer. Do i need a new transformer, can I cut the wirers on the existing oe
and joint it to a new one.
If you have a Digital or Electric shower these products will only operate with a live electrical supply so if they have cut out in use this could be because of an issue with the power supply.
If you have a Digital shower with a black processor box, there should be a green light on the top of the unit to indicate that it is receiving power. If the green light is off then it is unlikely that there is a fault with the product.
For all other Digital or Electric models it may be worth you carrying out the following checks:
MCBs (circuit breakers) may have tripped in the main ‘fuse box’ or consumer unit.
RCD may have tripped in the main ‘Fuse box’ or Consumer Unit.
Fuse may have blown within the switched spur (Digital or Power shower only). Your processor works on 240V, which should come from the property’s ring-main (not a lighting circuit) and the shower should have its own isolating switch called a fused switched spur. A fused switched spur resembles a light switch with a rectangular compartment on the front, which often says ‘FUSE’. These switches sometimes have a red/orange light and if this light is glowing, the power supply to the switch is live. If you find that your processor is unresponsive but the power supply seems to be working, you may want to try changing the fuse in the switched spur, which should be 3A.
Fuse may have blown within plug fitting (Digital or Power shower only). Sometimes installers choose to connect the power supply to a plug socket which contains a 3A fuse.
If there is a live power supply and adequate hot/cold water supplying the shower but you find it still will not start or continues to cut out then there may be a fault with the unit.
