Problem Solving
Symtom Solution
Unit filling to low level but not heating 1. Possible faulty PCB
2. Check Element
3. Check all wiring connections
Unit not filling 1. Check top probe (No.11 page 3) and ensure that the
probe is not in contact with tubing. Also check for
scale build up.
2. Check solenoid valve (No.1 page 3) with multimeter
set to K Ohms scale, it should read between
3.9 - 4.2.
3. Check water supply.
4. Turn pwer supply on then off to see if you can hear
the “squirt” of water from the solenoid valve.
Unit continually boiling 1. Replace thermistor steam sensor (No.4 page 3)
2. If above does not solve problem, replace PCB
(No.15a or 15b page 3).
3. Check the thermistor is positioned correctly.
Manual reset thermostat
(Unscrew) 1. Check water supply to tank.
(Element boil dry protection) 2. Check element.
3. Replace manual reset.
Tap leaking 1. Replace tap cup seal (No.15 page 3)
2. Replace tap assy (No.9 page 3). Re-tape with teflon.
Unit slow in “Heat/Fill” cycle 1. Water transfer hole in the cold water supply tube
may be blocked. Check and clear blockage.
( the hole is positioned above the thermistor sensing
probe, linking the cold supply and condensor tubes)
NOTE: Ensure all Earth connections are secure, failure to do so will cause the unit to operate irratically
