Triton Showers Troubleshooting – Frequently Asked Questions
Does the wiring to an existing electric shower need upgrading when fitting a higher kilowatt rated unit?
Not necessarily, it will depend on the existing cable size and installation characteristics. A site inspection by a competent electrician is required to confirm if the existing cable and fuse will need upgrading.
How can I work out the running cost of an electric shower?
To establish the electricity cost firstly multiply the kW per hour tariff you are paying by the kW rating of the shower. The cost per shower is then dependent on the number of showers taken per hour.
Example for an 8kW shower unit.
Electricity tariff at 12 pence per kW hour multiplied by 8 = Total cost of 96 pence per hour.
Number of 5-minute showers taken in 1 hour = 12
96p divided by 12 = Total cost of 8 pence for a 5 minute shower
If there is not enough mains water pressure to operate an electric shower what can be done?
When the mains water pressure is insufficient then a Triton T450i single impeller pump can be used to supply water to most electric showers. Alternatively an integral pumped shower such as the T90xr can be installed.
Note: pumped showers must be fed from a cold water cistern they must not be connected to the mains cold water supply.
What is the minimum water pressure and flow rate required for Triton Electric Showers?
The minimum water pressure required depends upon the model and its kilowatt rating.
Some units will continue to operate at a reduced flow performance on a minimum running pressure/flow of 0.5bar at 8 litres per minute. However for full flow performance from all electric showers the following pressure and flow is required.
•7kW to 8.5kW showers require a minimum running pressure of 1 bar at a minimum flow rate of 8 litres per minute
•9kW and 9.5kW showers require a minimum running pressure of 1 bar at a minimum flow rate of 9 litres per minute
•10.5 kW showers require a minimum running water pressure of 1.5 bar at a minimum flow rate of 11 litres per minute
What points need to be considered when replacing an existing electric shower?
Considerations when replacing an electric shower are:
•Dimensions of the unit (will the replacement shower cover existing tiles and screw fixings)
•Cable and water entry points (are they compatible)
•Kilowatt rating of the unit (is the existing cable and fuse size adequate for a higher kW rating )
•Incoming electricity supply to the property (is the supply adequate i.e. 80 or 100amp for a higher kW rating )
What size fuse do I require for an electric shower?
The fuse size must be equal to or the nearest size above the kilowatt rating of the shower i.e.
•7kW = 30/32amp mcb
•7.5kW = 32amp mcb
•8kW = 40amp mcb
•8.5kW = 40amp mcb
•9.5kw = 40/45amp mcb
•10.5kW = 45/50amp mcb
Which electric shower do you recommend as a replacement for an old one?
The T80z is recommended as a replacement for all previous models of T80 i.e. T80Mk3, T80i, T80si and T80xr.
When replacing a T80xr it may be necessary to purchase the T80z uni-fit kit, which enables the existing supply cable to be extended and connected to the main terminal block and earth post in the shower.
This T80z is also an ideal replacement for other makes and models as water and cable entry points are on both the left and right hand side of the unit.
Triton Showers Troubleshooting – How to Solve Your Triton Electric Shower Problems:
A newly installed T300si, when started the low water pressure light is on and there is only cold water from the shower head, why?
Check that the commissioning procedure has been carried out correctly as detailed in the fitting instructions. Ensure the inlet filter is not blocked and establish that water pressure and flow meets the specified minimum.
Having reset the MCB my electric shower is now not heating the water fully, why?
The most likely reason why the unit is not heating the water fully is that a heating element has failed. These elements can be tested for continuity using a multi-meter. If open circuit a new heater assembly is needed.
Note: If an element has failed other parts within the unit may have been affected it is therefore important to check all the electrical circuits in the unit for signs of failure.
My electric shower is indicating low pressure what should I check?
- Check isolation valves are fully open
- Ensure the inlet filter is not blocked with debris
- Check minimum required water pressure and flow is available at the inlet to the shower.
My electric shower runs hot then cold (cycling), why?
- The flow rate of water through the unit could be too low, causing the thermal cut-out to activate. Check there are no restrictions to the flow of water through the unit
- There could be a possible sudden drop in water pressure, falling below the minimum required. This could be because water is being drawn off elsewhere in the house e.g. the washing machine, or a toilet flushing.
My electric shower will not turn off the water what should I do?
- Check that the front cover has been fitted correctly with no distortion to the backplate
- On units fitted with a commissioning link, check that it has been removed during installation (see fitting instructions for further advice)
My Triton electric shower is under warranty and has a fault, what is the procedure?
If the shower is under warranty request an engineer visit via this site or call 0870 067 3333 to arrange a visit under the terms and conditions of the warranty
The water flowing from my electric shower is cold/too cool, what can I check?
Is electricity turned on to the unit?
- Ensure that the temperature control is set to the correct number for the time of year (you will need a higher number in the winter than in the summer)
- Check that the power selector (if available) is set to ‘High’
- For units fitted with a ‘Low Pressure’ indicator, check to see if it has been activated. If it has, then it is advisable to check for blockages in the inlet filter and/or have your mains water pressure checked
- On units not fitted with a ‘Low Pressure’ indicator, pressure could still be the problem, so it is advisable to have this checked prior to an engineer call-out
- Check that the front cover has been fitted correctly with no distortion to the backplate.
There is no water flowing from my electric shower, what should I check?
- Is water turned on to the unit?
- Has the electricity turned on to the unit?
- Is the inlet filter blocked?
- Are the front cover and any start/stop connecting cable fitted correctly?
Water from my electric shower is not getting hot enough, why?
Check the temperature control and power setting is on the correct setting for the time of year.
Make sure the temperature control (flow control valve) is regulating the flow of water through the unit, there should be a noticeable reduction in flow when turning towards the hotter settings.
Using an electrical test meter the following electrical components can be checked for continuity:
- Heating elements
- Thermal cut-outs
- If the unit is electronic then voltage tests have to be carried out on the PCB/s (printed circuit board/s) in the unit.
Water from my electric shower is too hot, why?
- Check that the Stop Tap is fully open
- Make sure that the sprayplate of the shower head is clean. Check if an acceptable temperature is achieved by removing the shower head from the shower hose
- Check the internal lining of the shower hose is not collapsed
- If the shower is delivering a flow of less than 5 litres/minute on a temperature setting of ‘1’, then check for blockages in the inlet filter. Use a bucket and stopwatch to check flow rate
- Finally if the problem is occurring during a period of hot weather, then you may be experiencing high incoming ambient water temperatures and /or borderline water pressure. Try setting the power selector (if available) to ‘Low’ and adjusting the temperature control to suit.
What is a PRD (pressure relief device)?
The PRD is a safety device designed to relieve abnormal pressure from within the heater assembly of an electric shower when a restriction occurs on the shower outlet i.e. blocked shower head, collapsed shower hose. If activated it will be necessary to fit a new one.
When I turn on my electric shower water starts leaking out from the bottom of the unit, why?
If water is leaking from a clear plastic tube or small plastic elbow in the unit, then the Pressure Relief Device (PRD) has been activated. The most common reasons for the PRD to activate are that the shower head has become blocked or there is a restriction in the shower hose. A replacement can be ordered from our online spare parts store or by calling 0870 067 3333
If the water is not leaking from the clear plastic tube, then isolate the electricity supply to the shower and call 0870 067 3333 for advice.
Where is the filter situated in a Triton electric shower?
The filter will be found in the inlet connection. In some units it will be necessary to disconnect from the water supply to access the filter.
Where is the serial number located on a Triton Electric shower?
A rating label is located on the underside of the unit, which includes the model name, kW rating and the manufacture date code (ACCEPTABLE FOR WARRANTY REGISTRATION). Inside the unit there is a further product-rating label, which has the same information and also the serial number.
