Tools Required :
Screwdriver x Phillips/star
Locking pliers x 2 (vise grip style
Silicone oil
Rags / Towel
Prevention / Maintenance :
Vinegar / Citric acid as descale or remove lime
Drain cleaner ( alkaline to dissolve oils and grease )
Problem: washer is very noisy during spin cycle.
Objects on or around the washer
My washer was making a rumble sound during the spin cycle. The troubleshooting process brought me to first think it was something on, or around the washer. I removed any objects, and checked that it was properly level. No change.
Bearings ?
Next I thought it could have been the bearings either in the motor or in the tumbler, after removing the paneling and turning it by hand, I couldn't feel or hear any resistance.
Drain Pump
Last, and the most easily accessible, was the drain pump. The front panel at the foot of the washer. Two screws needed to be removed.
As per this image, the bolts are at number 19.
With the washer disconnected from AC/shore power, I removed the plug to the pump motor, unscrewed two screws at the base, use locking pliers to open the pipe clamps on both inlet and outlet.
When installing the new pump, put some silicone oil on the inlet and outlet to make it easier for the rubber hoses to slip on - don't get any on your hand or tools. It's rather lubricious.
Assembly of a washer drain pump :
 |
| All the parts - laminated core, AC coil, cover, rotor cover. permanent magnet rotor core, impeller, impeller housing with inlet and outlet |
 |
| Put the coil over the laminate core |
 |
| Insert the housing in the laminate core |
 |
| Be careful - the magnet will draw the core into the housing very quickly The problem was here with water getting past the black seal of the shaft. |
 |
| Instead of replacing the whole unit, the pump rotor housing with rotor inside and impeller could have been replaced. |
 |
| Just replace this as a whole. Coil, laminate core and pump housing were fine. |
