12.4PUMP BLOCKAGE

Pump Block error is fault code 37. This is one of the most likely problems encountered in Smartdrive. See section 11.0 for more information on fault code 37.

Drain the Bowl. This can either be done using the pump or emptying the bowl manually.

If there is a service hatch (Phase 1-4). Remove the front inspection panel by inserting a screw driver into the slot and turn anticlockwise 1/8 of a turn. Pull outwards and remove.

Flick Starting the pump. Advance to SPIN and attempt to flick start the fan on the pump motor. This may alleviate the need to drain manually.

Draining Manually. Disassemble top deck, neck ring, agitator and inner bowl. Use a container to empty the bowl.

Check for foreign object by inspecting from above. Removing pump hood, cap and impeller. Check for obstructed drain hose.

Other Checks.

•Check pump hood, cap and impeller are the latest type. See WM013 in Appendix B.

•If the product is 5kg size check that a rain shield is fitted to the pump p.n. 426292.

•Check that the four bolts securing the pump bracket are tight, torque 3 Nm.

•If the screw locating the pump hood is loose, torque 3 Nm, this can cause pump block error.

To remove the pump, turn it towards the front of Smartdrive until the locking tab prevents further turning, then release the locking tab by pulling it away from the pump. Continue to turn, the pump will disengage. When refitting the pump, making sure that the bayonet fixture is located correctly. Twist the pump away from the front of Smartdrive until the locking tab clicks into place.

NB: Approximately 1 litre of water remains in the pump sump after pump out and can spill out when the pump is removed. However by tilting Smartdrive past 45 degrees and blowing down the drain hose this can be alleviated.

There is 230V AC at the pump terminals the whole time

Smartdrive is switched on at the power point.
