6.2.2 Drain Pump

The pump is a sealed unit and should not be dismantled. Instructions for removal /
replacement are as follows.

1) Place a bucket below the pump, to catch any
water remaining in the housing or pipework.

2) Remove the two screws holding the pump cover
& lift clear.

3)  Undo  the  three  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.

4) Fit the replacement pump by following the above
steps  in  reverse  order.  Ensuring  that  the  O-ring
surrounding  the  impeller  housing  is  correctly
seated,  and  that  it  mates  correctly  with  the  feed  /
drain manifold.
