10 SPECIALISED SERVICE PROCEDURES
10.1
Blocked Pump Procedure
It is possible to clear a blockage/obstruction from the pump without having to drain the water from
the machine or disturbing the pump. If however there are concerns over the condition of the water
and there may be a risk of infection, ie from hepatitis etc, then bail the water from the machine first.
While it is possible in some cases to be able to flick the pump from underneath the machine to
remove the obstruction, our recommendation is to carry out the procedure below which leaves the
pump undisturbed.
This way the object causing the obstruction can be identified, as well as the integrity of the pump
remains in tact.
(a) Follow procedure for removal of pump hood.
(Refer to Section 9.14).
(b) Remove pump cap.
(c) Locate object and check for free movement
in both directions of the impellor.
(d) Refit pump cap and pump hood, ensuring
that the seal is not pinched.
(e) If water is in the machine, enter diagnostic
mode and run the pump (Refer to Section
4.2) to drain the remaining water out of the
machine.
(f) Check for and remove any other foreign
objects that may be present in the bottom of
the outer basket.
Reassembly:
Refit in reverse manner.
