Descaling your hot water dispenser
Your hot water dispenser should be periodically de-scaled as the mineral
deposits in tap water may form scale within this product and cause the hot
water dispenser to operate less efficiently.
You can use a commercially available de-scaling agent and follow the
instructions on the packaging. Alternatively, you can follow the instructions
below using white vinegar.
1.
Fill the hot water dispenser with 300ml of white vinegar, then add water to
the MIN level.
2. Leave the solution in the hot water dispenser overnight.
3. Pour the contents of the hot water dispenser down the sink refer to
'Emptying your hot water dispenser' section, then fill the hot water
dispenser to the MAX mark with clean water.
4. Boil the hot water dispenser and discard the water.
5.
Repeat the boil process several times until the odour of the vinegar has
been flushed away.
6. Any stains left inside the hot water dispenser can be removed by rubbing
with a damp cloth.
Boil-dry protection
If you accidently let the hot water dispenser operate without water, the boil dry
protection will switch off the power automatically. This hot water dispenser is
protected from overheating. If this happens, remove the plug from the mains
supply and allow the hot water dispenser to cool for 40-60 minutes before
filling it with cold water and re-boiling.
