Billi Tap Troubleshooting FAQs

If your Billi Tap has stopped dispensing water:

• Check whether the building’s mains water supply has been interrupted or water pressure has dropped.
• Ensure the isolation valve supplying the under-sink unit is fully open.
• Check the power supply is switched on.
• Look for any warning lights or error messages on the display.
• If an error message is displayed, the system may require a reset or engineer assistance.

If these checks don’t resolve the problem, the system should be inspected by a qualified engineer.

If your Billi Tap is not heating water, check the power supply and display for error messages. If the red light keeps flashing after allowing time for the unit to reheat, contact Wellbeing Group to arrange support.

Should your Billi Tap fail to chill water, verify that the power is connected and the water inlet is functioning. A pulsing blue indicator shows the cooling cycle is active. If the issue persists, please reach out to Wellbeing Group for assistance.

Chilled water may feel warm while the system recovers after heavy use or restarts. Check whether the blue light is flashing. If cooling does not complete, arrange professional servicing promptly.

Yes. After power returns, switch the Billi Tap on and allow it to reheat and chill. If it remains locked or unresponsive, follow approved reset instructions or contact technical support.

If your Billi Tap displays “Locked Off” after being unused for an extended period (such as after an office closure), follow these steps:

• Turn the unit off at the mains for 30 seconds.
• Turn it back on and wait around 15 minutes.
• Wake the display by pressing the Back button if the screen is blank.
• If the display reads “Locked Off,” press and hold the Mode button until “Locked On” appears.
• Allow up to 25 minutes for the unit to heat and chill.
• Once the red and blue lights become solid, test both boiling and chilled water.
• If required, return the unit to Time Switch ON mode.

When your office will be closed for an extended period:

• Switch off the electrical supply.
• Isolate the water supply if recommended for your installation.
• When returning, switch the water supply back on before restoring power.
• Allow the unit time to fully reheat and chill before use.
• If the unit displays Locked Off, follow the reset procedure above.

This is normally part of the system’s operating cycle.

• Flashing red means the boiling water has not yet reached operating temperature (99°C).
• Flashing blue means the chilled water has not yet reached its set temperature.
• Once both temperatures have been reached, the lights become solid.

Flashing yellow lights indicate that the system has detected a fault.

If the yellow lights continue flashing:

• Do not attempt further diagnosis beyond basic checks.
• Contact a Billi service engineer for technical support.
• An engineer visit may be required if the fault cannot be resolved remotely.

Common indicators include:

• Flashing Red = Heating Water
• Flashing Blue = Chilling Water
• Solid Red & Blue = System Ready
• Flashing Orange = Filter Replacement Due
• Solid Orange = Filter Overdue
• Flashing Yellow = System Fault

If your Billi tap is going to be unused for an extended period, shut the system down correctly to help prevent leaks, stagnant water and problems when it is brought back into use.

1. Switch the Billi system off at the power supply.
2. Turn off the mains water supply to the unit using the relevant isolation valve.
3. Allow the system to cool before carrying out any further checks or draining.
4. Drain the system in line with the instructions for your specific Billi model. Do not dismantle the under-counter unit unless you are suitably qualified.
5. Leave the Billi switched off and isolated from the water supply while it is not in use.
6. When recommissioning the system, turn the water supply back on first and allow the unit to refill before restoring power.
7. If the Billi tap has been unused for several weeks, arrange for the system to be flushed, sanitised and checked before returning it to normal use.

The exact shutdown and recommissioning process can vary between Billi models, so always follow the manufacturer guidance for your system. If you are unsure how to safely decommission or restart your Billi tap, contact Wellbeing Group service team.

If your Billi Tap System displays ‘locked off’ after being inactive for several weeks, such as over Christmas or following relocation, you may need to complete the Billi reset procedure.

A beeping Billi Tap may indicate a system alert or fault. Check the under-counter display for an error code, then contact Wellbeing Group if the alert continues or requires support.

Safety Mode helps prevent accidental dispensing of boiling water.

To enable it:

1. Press Select on the under-sink controller.
2. Navigate to Options.
3. Set Safety Switch to On.
4. When enabled, touch the sensor on the rear of the tap before dispensing boiling water.

If water is leaking from either the tap or the under-sink unit:

• Switch the power off immediately.
• Isolate the water supply.
• Do not continue using the tap.
• Arrange for a service engineer to inspect the system.

A continuously flashing red light combined with no boiling water may indicate:

• The unit is still heating.
• The heating element has failed or overloaded.

Reduced chilled water flow is usually caused by a blocked filter. As filters trap contaminants, they gradually become restricted, reducing water flow while the boiling water may continue operating normally.

Billi recommends replacing the filter:

• Every 12 months
• Or after approximately 30,000 litres of water

After switching on, a Billi Tap can take up to 25 minutes to reach boiling and chilled temperatures, depending on model and capacity. Solid red and blue lights indicate readiness.

Your Billi Tap may turn itself off because its time switch or energy-saving mode is active. Check the under-counter display and settings. If shutdowns continue unexpectedly, contact Wellbeing Group for assistance.

A brief hum or buzz can be normal while the Billi Tap heats, chills or pumps water. If the noise becomes loud, constant or unusual, contact Wellbeing Group for a professional inspection.

Remove the empty CO₂ canister by unscrewing it from the regulator. Remove the red cap from the replacement canister, screw it in tightly, expect a brief gas release and check for 2.5–3 bar.

If sparkling water stops dispensing, check the unit has power, the water supply is on, and the CO₂ canister is not empty. Note any display error, then contact Wellbeing Group.

If sparkling water dispenses but lacks fizz, check the CO₂ canister is not empty and the regulator reads 2.5–3 bar. Replace the canister if needed or request support from Wellbeing Group.
