Drain pump
The drain pump is a sealed unit and should not
be dismantled. To remove / replace the pump:-
1. Place a bucket below the pump to catch any
water remaining in the housing or pipework.
2. Undo the screws holding the pump body
to the feed & drain manifold and remove
it - any water trapped in the pump will be
released at this point.
3. Fit the replacement pump by following the
above steps in reverse order. Ensure that the
pump is correctly seated and that it mates
correctly with the feed / drain manifold and
gasket.

Bottom access panel
An access panel has been provided at the
bottom of the unit, held in place by screws.
Removal of the panel allows access to the drain
pump and feed / drain manifold assembly.

Solid State Relays (SSRs)
A faulty SSR should be replaced with an SSR of the
same (or higher) voltage and amperage rating.
To replace an SSR:-
1. Ensure the I/O/II on the fascia of the unit is in the
'0' (Off) position.
1. Disconnect the unit from the electrical supply.
2. Disconnect the SSR and undo the mounting
screws. The SSR is bedded in thermal compound
to assist heat transfer – it is important that this
is cleaned off and a layer of fresh compound
placed under the replacement SSR, when it is
secured in position.
3. Reconnect the SSR, reconnect the electrical
supply and check the SSR function (as above)
before replacing the access panels.
Use proprietary thread locking compound on the line
voltage terminals of the SSR’s.
