Troubleshooting | Kelda Showers

Shower system does not operate

Problem

Cause

Solution

Shower system does not operate fully (reduced or no water flow)

Hot or cold water supply isolation valve closed.

Debris has caused blockage in mixer.

Pressure difference between hot and cold supplies is too high.

Shower mixer/valve not functioning.

The disinfection process has caused debris in the form of corroded metal or scale to lift from the system pipework and cause the solenoids to block.

Check and open valve.

Isolate mixer and service strainers and cartridge see mixer instructions to service.

Adjust screws on mixer to balance. Or fit pressure reducer on high pressure supply.

Check valve, replace if necessary.

During the flushing of the pipework with the chemical present, as well as when coming to flush out the chemical back to freshwater, the Kelda Showers should be left until the last outlets in the building to flush, ensuring all tap outlets, bib taps and dead-legs have been flushed until there is no debris or discolouration present in the water. You may also have Group or Single outlet mixers before the showers, these will need to have the filter/strainers checked and cleaned. Failure to do this may result in the blockage of solenoids, causing them to either stick in the open position or not pass water.

If the solenoid valve in the Kelda Shower has become blocked it will need to be replaced.

Water flows from shower head but no air

Problem

Cause

Solutions

Water flows from shower head but no air

Does the fan run?

Is the LED in front of the Control Hub illuminated?

Debris in fan.

If so, check seal of air hose connections and that hose is kink free.

If no, check electricity supply.

Conduct hard reset by switching off electrical supply and waiting 10 seconds before turning on.

Clear any debris from fan and follow Fan Test Function in Instruction Manual.

If fan runs, then check flow sensor is not jammed or faulty.

Temperature fluctuating

Problem

Cause

Solution

Temperature fluctuating

Thermostatic control/Boiler issue.

Check thermostatic mixer valve/boiler for an issue, call a specialist if necessary.

Poor/no water flow

Problem

Cause

Solution

Poor/no water flow

Blocked water filter/strainer

Disconnect water inlet hose, remove and clean filter, replace filter.

Water flow too strong

Problem

Cause

Solution

Water flow too strong

Flow restrictor not installed.

Check if the flow restrictor is properly installed (adjacent to the water inlet).

Outlet temperature too cold

Problem

Cause

Solution

Outlet temperature too cold

No hot water reaching valve.

Filter blocked.

If the fault has been present since the valves have been installed, it is possible that the inlets were installed incorrectly.

The water supply will be colder in winter months due to outside temperature.

Check the water supply for any outside blockages.

Remove filters and clean.

Check installation – hot on the left, cold on the right.

It may be necessary to adjust the hot water supply. i.e. increase the hot water temperature setting on boiler.

Outlet temperature too hot

Problem

Cause

Solution

Outlet temperature too hot

No cold water reaching valve.

Filter blocked.

If the fault has been present since the valves have been installed, it is possible that the inlets were installed incorrectly.

The water supply will be hotter in winter months due to outside temperature.

Check the water supply for any blockages.

Remove filters and clean.

Check installation – hot on the left, cold on the right.

It may be necessary to adjust the hot water supply. i.e. increase the hot water temperature setting on boiler.

Only hot or cold water from valve outlet

Problem

Cause

Solution

Only hot or cold water from valve outlet

Possible the inlets have been installed the incorrect way around.

If only cold water is coming out the mixer, it is possible there is a cartridge fault.

Filters blocked.

Check the inlets are installed correctly – hot on the left/cold on the right.

Remove and check the condition of the thermostatic cartridge.

Remove the filters and clean.

Cannot adjust temperature

Problem

Cause

Solution

Cannot adjust temperature

Possible that the cartridge is sticking due to limescale build up.

Override temperature manually.

Remove the thermostatic cartridge and service.

Remove the temperature handle by removing the end cap and centre retaining screw. Turn the flow of water on fully and turn the cartridge spindle anti clockwise to increase the water temperature, and clockwise to decrease the water temperature.

Poor flow rate

Problem

Cause

Solution

Poor flow rate

Insufficient water pressure.

Filters partially blocked.

Flow valve not fully opening.

The required minimum water pressure is 0.5bar (5Mpa).

Remove filter and clean.

Remove and check the condition of the flow valve.

Water leaking from the showerhead when the valve is turned off/closed

Problem

Cause

Solution

Water leaking from the showerhead when the valve is turned off/closed

This could be normal for a short period of time after the shower has been used.

Check that the water pressure doesn’t exceed of that of the product.

Flow valve leaking.

Solenoid is blocked in the open position.

N/A

If pressure is too high, adjust if necessary. Refer to technical data.

Remove and check the condition of the valve.

Due to the corrosive substances used in the disinfection process, there can be debris in the form of corroded metal or scale lifted from the system pipework. For this reason, due to the flushing of the pipework with the chemical present, as well as when coming to flush the chemical back to freshwater, the Kelda Showers should be left until the last outlets in the building to flush, ensuring all tap outlets, bib taps, and dead legs have been flushed until there is no discolouration present in the water. You may also have Group or Single outlet mixers before the showers, this will need to have the filters checked and cleaned.

Failure to do this may result in the blockage of solenoids, causing them to either stick in the open position or not pass water.

Water leaking from shower/valve controls

Problem

Cause

Solution

Water leaking from shower/valve controls

Leaking from flow valve.

Leaking from thermostatic cartridge.

Check that the pressures do not exceed that stated for the product.

Remove and check the condition of the flow valve.

Remove and check the condition of the thermostatic cartridge.

Check that the pressures do not exceed that stated. If pressures are too high, adjust as necessary. Refer to Technical Data.
