why does my Simpson SWT951 washing machine show E20?
E20 on the Simpson SWT951 top loader is a drainage warning. a restricted drain hose or another internal drainage fault may be involved; it does not identify a failed motor.
model scope: Simpson SWT951 top-load washing machines.
pause the machine and check only the already visible drain hose for kinks or obstruction without moving the connected appliance. record whether the washer stopped with water inside and whether it had reached the spin stage.
if it still will not empty, arrange service using the linked pump-checking guide. leave panels closed, do not force the lid or investigate a running pump, and do not borrow a lower-front filter procedure from a different washer.
any motor replacement needs separate matching of the old motor and the product page's documented fitment. this guidance is for SWT951 only; use its own code table rather than a later top-loader's filling or water-loss instructions.
possible causes
- restricted drain hose or drain path
- a failed pump motor or another internal drainage fault
