Problem Solving

Symtom
Unit filling to low level but not heating
Unit not filling
Unit continually boiling
Manual reset thermostat
(Unscrew)
(Element boil dry protection)
Tap leaking
Unit slow in "Heat/Fill" cycle
NOTE: Ensure all Earth connections are secure, failure to do so will cause the unit to operate irratically
Solution
1. Possible faulty PCB
2. Check Element
3. Check all wiring connections
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.
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.
1. Check water supply to tank.
2. Check element.
3. Replace manual reset.
1. Replace tap cup seal (No.15 page 3)
2. Replace tap assy (No.9 page 3). Re-tape with teflon.
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)
