Pronteau Mixertap Issues & Likely Faults
Troubleshooting Tips

Mixertap Issue:Likely fault(s):Action to take:
Slow domestic hot water flow. Aerator is blocked or partially blocked due to debris or scale.
Domestic hot water pressure is from a gravity fed system and is lower than the stated recommended minimum.
Remove aerator - clean and replace. (see cleaning section of user guide)
Add a booster pump to the hot water cylinder to improve hot water flow.
Mixed water temperature is too cool. Water pressures are unbalanced, hot water pressure is less than cold. Reduce the pressure or flow of unfiltered cold water to the tap to nearer balance the pressures.
Domestic hot water temperature is too low. Increase the boiler output temperature to help compensate.
Water is spraying from the spout end. Aerator is blocked or partially blocked due to debris or scale. Remove aerator - clean and replace.
(see cleaning section of user guide)
Water dripping from centre channel on the spout when not in use. Flexible hose from tap to boiler does not have a constant fall back to the boiler. Check the flexible hose is not looped, kinked and has a constant fall to the boiler
Water dripping from outside channel on the spout when not in use. If the water does not constantly drip, this is water remaining in the spout releasing under gravity. None - this is normal.
If the water does constantly drip the tap valves most likely need replacing. Contact the service agent for replacement valves.
Water leaking between the tap body and the spout. Damaged or worn spout 0-rings. Contact the service agent for replacement spout 0-rings.
No heated water is dispensed when the Hotkey is placed near the tap. The data wire connecting the tap to the boiler is disconnected. Follow the wire from the tap to boiler. Check the plugs are firmly connected.
The data wire connecting the tap to the boiler is damaged. The wire to or from the boiler needs replacing. Contact the service agent for parts.
The boiler is not switched on. Check the boiler has power and the display is not showing any error messages.
The boiler is not heating to the requested temperature. Wait for the boiler to fill and heat until a constant 'READY' message is displayed.
The entire tap moves when used. The tap fixing nut is loose and or gaskets from the fixing kit have been missed out of the assembly. Check all the gaskets listed in the tap instructions are present. The tap is relocated centrally, then tightened fully using a basin wrench or box spanner.
