Repairs this series usually needs
- Fill error that stops the cycle
- Drain alarm with water left behind
- Coin slide that sticks or rejects
- Control that ignores programming
- Motor overload that stops agitation
The SWT4 to SWT9 prefixes bring together 54 older Speed Queen top-load numbers, including SWT422*N and SWT911*A3000. They sit between the large SWT1 and SWT2 blocks and the letter-coded SWT numbers, and the data plate shows which one you have.
The control behind these numbers may be a timer, an EDC board or an MDC or NetMaster control, so the first job is to find out which one is fitted. The fill and drain error messages are similar from one to the next, and so are our tests: valves and screens for fill, pump and hose for drain, switch and motor for a washer that stops.
Some of these machines are very old, and a few have changed hands more than once. You see the estimate before work begins, and honest advice comes with it when replacement is the smarter move.

SWT4, SWT5, SWT6, SWT7, SWT8 and SWT9. They are older top-load washers, and we confirm parts for the full model number on your data plate.
What do the fill and drain errors on older controls mean?
A fill error means the tub did not reach its level in the allowed time, and a drain error means water was still present when it should have gone. We check supply and drain paths before the control.
Will you repair a very old washer?
If parts can be found and the repair makes sense against the washer's value, yes. We check parts availability for the full model number before the visit, so you do not pay for a trip that leads nowhere.
