Troubleshooting

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

Hot or cold water supply isolation
valve closed.

Check and open valve.

Debris has caused blockage in mixer.

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

Pressure difference between hot and
cold supplies is too high.

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

Shower mixer/valve not functioning.

Check valve, replace if necessary.

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.

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

Does the fan run?

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

Is the LED on the front of the Control
Hub illuminated?

If no check electricity supply

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

Debris in fan

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

Thermostatic control/Boiler issue.

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

Poor/no water flow

Blocked water filter/strainer.

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

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

No hot water reaching valve.

Check the water supply for any blockages.

Filter blocked.

Remove filters and clean.

If the fault has been present since the valve was installed it is possible that the inlets were installed incorrectly.

Check installation-Hot on the left /cold on the right.

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

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

Outlet temperature
too hot

No cold water reaching valve.

Check the water supply for any blockages.

Filter blocked.

Remove filters and clean.

If the fault has been present since the valve was installed it is possible that the inlets were installed incorrectly.

Check installation-Hot on the left /cold on the right.

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

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

Only hot or cold water from valve outlet

Possible that the inlets have been installed the incorrect way around.

Check that the inlets are installed correctly-Hot on the left/cold on the right.

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

Remove and check the condition of the thermostatic cartridge.

Filters blocked.

Remove filters and clean.

Cannot adjust temperature

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

Remove the thermostatic cartridge and service.

Override temperature
manually.

Remove the temperature handle by removing the end cap and center 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

Insufficient water pressure.

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

Filters partially blocked.

Remove filter and clean.

Flow valve not fully opening.

Remove and check the condition of the flow valve.

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

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

N/A

Check that the water pressure does not exceed of that stated for the product.

If pressures are too high adjust as necessary. Refer to Technical data.

Flow valve leaking.

Remove and check the condition of the flow valve.

Solenoid is blocked in the open position.

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, 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.

Water leaking from shower valve/controls

Leaking from flow valve.

Remove and check the condition of the flow valve.

Leaking from thermostatic cartridge.

Remove and check the condition of the thermostatic cartridge .

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

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