Hi, I was hoping somebody could point in the right direction with a fault that has recently occurred with my electric shower. The shower is a Bristan Glee 9.5kw which we have had for about 5 years. The shower was working fine until about a month ago when the shower started turning off, seemingly randomly.At first it wouldn't happen very often and if you waited (without pressing any buttons) it would come back on. However recently it has been doing it much more frequently and the waits are much more longer, it is like playing Russian roulette in the morning. I've tried turning it on and off at the shower and at the pullcord but it doesn't seem to make much difference. It seems to do it even when nobody is using any of the taps so I don't think it would be low water pressure. Also when the shower goes off, the light does not go off at the pullcord. Any pointers for what the problem is would be appreciated, thanks.
Very likely it's an overheat 'stat tripping on the heating cannisters. Do you like your showers hot?! Possible causes? I guess a restricted water flow is the most likely. Can you check if there's an inlet water filter in the shower? Also check the shower head to see if it's scaled up - do you have hard or soft water? Try running the shower on a lower setting - that upper knob on 1 or 'eco' - and see if it runs ok like this.
scaled up heater can? as its 5 yrs old? you in a hard water area? wiring fault inside shower, loose /burnt connection.Does it just stop running or go cold? We're like doctors , the more you tell us!
A 5 yr old electric shower starts to play up, too much inside, replace it for what they are now, this outfit do a 8.5KW shower for £50.00
I had a 10.8 kw in last place....and it was only just acceptable in the winter....with a half decent flow. Wonder why they make anything bigger than 8.5 kw if they are sufficient ? RS
Depends what you expect from a shower....if you're used to high flow rate rain head type showers fed from a pumped cylinder or combi, an 8.5 is going to feel like warm **** on full bore.
It was a vague reference to the Yorkshiremans sketch by Monty python, but i know where you are coming from RS
The water flow probably gets restrained which in turn makes the shower go off. Check with the water flow.
Having reread the op, goes on and off would suggest a terminal somewhere is overheating/ burning , either in shower or switch poss
Thermal cutout on top of heater-can self resets. A shower running hot/cold constantly is nearly always due to the thermal cutout tripping in/out. This is usually due to low flow, due to poor pressure, blockage, scale etc. Check filter, clean shower head. The low pressure neon would also usually illuminate, if present.
Could also be the loose terminal/poor connection in the pullcord switch. Neon won't always go out if there is still some connection but not enough to supply shower. Mr. HandyAndy - Really
