Wickes Aquatronic 2 Shower

Hi all, need help with Wickes Aquatronic 2 shower.

I installed one and ever since have had problems with the water shutting off and the circuit breaker tripping. The temperature setting is fairly low just warm for a shower. (about 6 out of 10 for WARM selection) The model has 3 sellections: Cold, WARM and Hot) If a lower selection is made, say 4 or 5, the shower, works for longer time, but eventually shuts down. Any ideas?? Any suggestions welcome. Thanks

PS: The removed (old) shower, had a similar problem, though not as bad, but was removed because limescale was suspected.

what setting is it on when it trips 1 red marker or 2 red marker ?
does it still trip if run on the blue marker ?

Hi, Thanks for coming back. The setting is always on 1 red (red 2 is too hot and trips almost straight away beyond the 3 selection out 10) On cold setting, I have not had it running too long so have not experienced a cut off.

the cold setting shouldn't trip at all.
sounds like you got a heating element fault.
try doing a resistance test on both pairs.
should read 10 - 18 ohms each.

Hi,

Many thanks. I will carry out the resistance check.

By the way, when the consumer unit was first fitted, the RCD used to trip off whenever there was the slightest thunder/lightning in the area!! After a while the the RCD was changed as it was too sensitive, and has behaved well since then. Getting back to my present problem, I have another electric shower which is also tripping, (trips straight away after switching on) but only started this trend after 3 to 4 years from installation. I put this down to limescale and is presently out of use. However, I am wondering if the circuit breakers are faulty? (When a bulb blows the lighting circuit breaker trips) I have MK LN5940 (40 amps) fitted on both showers. Any thoughts? Many thanks.

what kw is the shower ?

Its a Wickes Aquatronic 2 Ultra rated at 8.5kW which is fitted. There is also a 9.5kw model available and the spec says 40 amp fuse for both of them.
