| 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. |
