Leaks & Drips

Water flow rate / stream quality:

Proboil Issue: Possible Issue & Solution:
98°C Water flow rate is slower than expected. Note: the typical flow rate is between approximately between 1 and 2 litres per minute depending on your incoming cold water pressure and tap type, refer to the tap specification sheet for more detail. The boiler could be calcified: follow the boiler descale procedure in this manual.

Your incoming cold water pressure could be too low: test your incoming cold water pressure and compare it to the minimum required pressure.

Your filter cartridge could be partly blocked with debris: connect the blue flexible pipe from the filter inlet directly to the boiler (bypass the filter) to confirm, if needed replace the filter.

Your boiler inlet could be partly blocked with debris: with the water isolated remove the blue inlet wingnut (G) and inspect the meshed inlet seal (H) underneath, clean if required.

The aerator on the tap end could be partly blocked with debris or calcified: follow the aerator descale procedure in this manual.
98°C water does not stop the instant the 98°C handle is turned off. It is normal for a short delay after the handle is turned off for water to stop flow as the pressure remaining in the filter and boiler tank equalise.
98°C water does not start the instant the 98°C handle is turned on. It is normal for a short delay after the handle is turned on for water to start flowing as the tap empties partly after each use.
Water splashes sideways or irregularly from the spout end The spout aerator may be blocked or calcified, see “descalingaerator” section for more detail.
Water flow rate is faster than expected or is splashing The aerator on the tap could be partly blocked with debris or calcified: follow the aerator descale procedure in this manual.

Your incoming cold water pressure could be too high: test your incoming cold water pressure and compare it to the recommended and maximum required pressures, install a pressure reducing valve to your cold water mains supply if needed.

Follow the “Using the product safely” section of this manual: turn on the 98°C water handle only partly during use.

Water temperature:

Proboil Issue: Possible Issue & Solution:
Water temperature is lower than expected. The boiler has not started its reheating cycle after its last use: the boiler shows “READY” because only a small amount of water has been used and it takes a few minutes for the boiler temperature to equalise and then start its reheat cycle. The boiler has not completed its reheating cycle after its last use: the “HEATING” indicator is still showing during use
Water temperature is lower than expected. There has been a power cut (interruption to the power supply) the boiler automatically turns back on into standby mode. press and hold for 1.5 seconds to revert to normal mode. Follow “Periods of non-use” (1.1.5) guide to ensure water is heated.
Water temperature is lower than expected. The centre spout tube in the tap may be disconnected from the aerator, see “descaling-aerator” section for more detail.
Proboil Issue: Possible Issue & Solution:
no display illuminated (only displaying ) Unit is in standby mode: press and hold for 1.5 seconds to revert to normal mode.
no display illuminated (including no ) No power: Check mains socket is on, check fuse in boiler plug, check plug and socket on boiler left hand face is fully engaged.
Keys do not respond when touched Screen is dirty or wet: clean the screen with a damp soapy non abrasive cloth then dry. Ensure hands are dry when pressing keys. Also please make sure clear film is removed (if applicable).
Error “E” code displayed on screen E3 – no water in boiler, fill / flush with water, message will self clear

Leaking from the Boiler

Issue: Possible Issue & Solution:
Water is leaking from the boiler The boiler could be leaking from between the inlet adaptor and the boiler inlet: Remove the inlet adaptor (G) and check that the internal flat rubber seal is present internally and that rubber meshed seal (H) is also present, undamaged and seated correctly. When reconnecting the inlet adaptor (G) do not overtighten.

The boiler could be leaking from between the outlet adaptor and the boiler outlet: Remove the outlet adaptor (J) and check that “flat” rubber seal (I) is present, undamaged and seated correctly. When reconnecting the adaptor (J) do not overtighten.

Water dripping from the spout end when the handle is in the off position:

Issue: Possible Issue & Solution:
Water is dripping (continuously from the centre channel of the spout end aerator). The hot water on/off valve is leaking, to confirm the fault:

1) Turn the boiler into standby mode, press and hold the key for 1.5 seconds to activate.
2) Turn the 98°C tap handle off fully.
3) If the water continues to continuously drip or leak the boiling water valve needs to be replaced.
Water is dripping (continuously from the outer channel of the spout end aerator). The standard hot and or cold water on/off valve is leaking, to confirm the fault:

1) Isolate the hot and or cold water supplies leading to the tap in turn, to see if the dripping stops or not.
Water is dripping (intermittently from the centre channel of the spout end aerator). Most typically whilst the boiler is reheating The expansion chamber in the boiler may be full:

1) Turn the boiler target temperature to 75°
2) Turn the 98°C tap handle on fully, run for at least 2 litres continuously to self-empty the expansion chamber.

The incoming cold water pressure is less than 1.5 bar, at low pressures the expansion chamber will not self empty correctly, use a pressure gauge or use the tap specific flow test on cold water only to confirm the incoming pressure.
Water is dripping (intermittently from the centre or outer channel of the spout end aerator typically shortly after each use). This is water retained within the spout falling due to gravity and is normal for any tap
