PUMP 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.
- 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.
SHAFT AND BARING REMOVAL
- Fit the spline tool over the shaft. Remove the 1 1/4"AF shaft retaining nut securing the shaft.
- Lay the outer bowl on its side before removal of the shaft. This ensures that the shaft does not fall directly onto the floor.
NB:
The shaft can only be removed towards the inside of the outer bowl. Remove
the shaft. If the shaft is difficult to remove, use a puller and a mandrel.
Refit the thick stator motor clamp plate onto the outer bowl and secure with
the four stator mounting bolts. The stator clamp plate may be used to hold the
legs of the puller in place.
WARNING:
Make sure the stator clamp plate is flat before using. If in doubt, replace.
- Remove the outer bearing using the bearing removal tool.
WARNING:
Do not remove the bearings with a hammer and drift as serious damage to the
bearing housing or outer bowl may result. Use the bearing removal tool as
illustrated:
- Remove the seal with the aid of a screwdriver handle levering from side to side.
- Remove inner bearing using the bearing removal tool. Insert the threaded rod and extractor washer up from the bottom of the outer bowl. Place the collar and large locating spigot on the threaded rod and extract the bearing.
SHAFT AND BARING ASSEMBLEY
- The bearings must be inserted separately with the inner bearing fitted first and pulled down with the bearing tool onto the shoulder in the bearing housing. IMPORTANT: There must be no gap between the bearing outer race and the shoulder of the aluminum extrusion. Remove the insertion tool at this point and check that the inner bearing is fully home.
- Fit the bearing spacer and press in the outer bearing using the bearing tool. Check the spacer has no end float but has slight sideways movement to allow for shaft insertion.
- Ease the shaft through the bearings from inside the outer bowl. Take care the shaft is fitted with the threaded retaining nut section facing downwards in the direction of the base.
- Fit the shaft retention nut. Use the spline tool and spanner to tighten the shaft retention nut.
- Invert the outer bowl. Take care not to damage the shaft or flooring. Fit the assembly thimble sleeve onto the shaft before fitting the seal. Lubricate the seal outside diameter with liquid detergent and then slide into position by pressing down on both sides of the seal.
NB:
The seal should be flush with the lip on the base of the outer bowl.
TROUBLESHOOTING FLOWCHART
- This is a flow chart for original Phase 1 Smartdrive Motor Controllers and Displays. These are fitted with a slow blow 32mm 6A fuse. Use this flow chart when there is no power to the display module and Smartdrive is powered on.
