Water Dispenser Troubleshooting FAQs

Check that the dispenser is switched on, all visible leads are connected and no switches have been turned off. If you have a mains-fed machine, make sure the water supply is available and hasn’t been isolated. Heavy use can also temporarily affect dispensing, so give the machine a little time before trying again. If there is still no water, arrange an engineer visit.

Make sure the machine has power, the leads are connected and the compressor switch is on. If the dispenser has been used heavily, the chilled water supply may simply need time to recover. After switching the compressor on, allow around 15–20 minutes for the internal tank to chill. A particularly warm room can also affect performance. If the water still isn’t chilling, contact an engineer.

If water is still dispensing but feels warmer than usual, recent usage may be the reason. After a busy period, the machine needs time to chill the next supply of water. The room temperature can have an effect too, especially if the dispenser is positioned somewhere unusually warm. If the temperature doesn’t improve after the machine has had time to recover, arrange a service visit.

First, make sure the dispenser has power and that all visible leads are connected properly. After heavy use, the machine may need a little time to heat the next supply of water. If it usually provides hot water later in the day but not first thing in the morning, sleep mode may be involved and the settings may need checking. If the problem continues, arrange professional support.

Turn off the water supply to the machine as soon as you notice a leak. Where it is safe to do so, dispense any remaining water into a suitable container. Check the drip tray as well, as an overflowing tray or dripping tap can sometimes look like a leak from the machine itself. If the tray keeps filling or water is coming from elsewhere on the dispenser, stop using it and contact an engineer.

If your workplace is going to be closed for an extended period:

1. Switch the dispenser off at the mains.
2. Turn off the water supply to the machine.
3. Drain as much water as possible through the taps into a suitable container. Take particular care when dispensing hot water.

Following the correct shutdown process helps protect the dispenser while it is out of use and can reduce the risk of problems when the office reopens.

Turn the water supply back on before restoring the electrical power. Powering the machine without a water supply can damage the inlet valve. Once the dispenser is switched on again, allow enough time for the water to heat or chill before assuming there is a fault.

If the dispenser has been out of use for several weeks, Wellbeing Group recommends having it sanitised before it goes back into normal use. Rather than trying to clean the internal system yourself, arrange professional water dispenser maintenance so it can be sanitised and checked properly.

If your water cooler or dispenser is going to be unused for an extended period, it should be shut down correctly to reduce the risk of leaks, stagnant water and unpleasant odours.

1. Switch the power off at the mains.
2. Turn off the water supply to the dispenser. This will usually be via the isolation valve where the machine connects to the mains water supply.
3. Drain as much water from the dispenser as possible using the dispensing taps. Take extra care when draining hot water.
4. Leave the machine switched off and isolated from the water supply while it is not in use.
5. Before switching the machine back on, turn the water supply on first. This helps ensure the system refills before power is restored and reduces the risk of damaging components such as the inlet valve.
6. If the dispenser has been unused for several weeks, arrange for sanitisation before returning it to normal use.

If you are unsure how to shut down or restart your dispenser safely, contact Wellbeing Group service team for support.

If your hot water boiler is going to be unused for an extended period, shut it down correctly to help prevent leaks, stagnant water and damage when it is switched back on.

1. Switch the boiler off at the mains.
2. Turn off the water supply using the isolation valve connected to the unit.
3. Allow the water to cool before draining.
4. Drain the boiler as fully as possible in line with the manufacturer’s instructions.
5. Leave the unit switched off and isolated from the water supply while it is not in use.
6. When bringing the boiler back into service, turn the water supply back on and allow the system to refill before restoring power.
7. If the boiler has been unused for several weeks, arrange for it to be cleaned, sanitised and checked before normal use resumes.

Take extra care when working around stored hot water. If you are unsure how to safely shut down, drain or recommission the unit, contact Wellbeing Group service team

Check that the mains water supply is running normally and that the dispenser’s water supply hasn’t been partially or fully isolated. If both are fine, it is also worth checking whether the filter is due for replacement, as its condition can affect water flow. You can view our water dispenser filters or arrange a service if the problem continues.

Commercial water dispensers can only heat or chill a certain amount of water at one time. After an unusually busy period, the machine may need time to replenish the tank and bring the next supply back to temperature. If it returns to normal after a short recovery period, there may be nothing wrong. If the same issue keeps happening during everyday use, it should be checked by an engineer.

If your dispenser has stopped producing sparkling water, check the CO₂ canister first to make sure it isn’t empty or disconnected. It is also worth checking that the machine has power and that all visible leads are connected. If the dispenser has been heavily used, give it a short period to recover. If the problem remains, arrange an engineer visit.

Weak carbonation can be a sign that the CO₂ supply is running low or isn’t connected correctly. Check the canister and its connection, but don’t adjust any pressure settings or internal components. If the water is still flat and there appears to be enough CO₂, the dispenser should be checked by an engineer.

If sparkling water becomes noticeably flatter or stops dispensing altogether, the CO₂ canister may be low or empty. Wellbeing Group supplies replacement canisters for sparkling water dispensers, which you can find with our water dispenser accessories.

Yes, it can. Filters are consumable parts and need replacing at the right intervals. If water flow has reduced and the filter is due for a change, it is worth checking, although low flow can have other causes too. Always use the correct filter for your dispenser and follow the relevant replacement guidance.

Wellbeing Group’s maintenance plans include preventative servicing and sanitisation every six months, along with scale management and scheduled filter replacement. Regular servicing keeps routine maintenance on track and gives an engineer a chance to spot developing issues before they become bigger problems.

Call an engineer if a leak persists, the dispenser still won’t heat or chill after the basic checks, no water is coming through despite the machine having power and a water supply, or a sparkling water fault remains after checking the CO₂. Recurring problems and anything involving internal electrical, refrigeration or pressurised components should also be left to an engineer.
