- Check the hoses and connectors for leaks, cracks and splits, and tighten the hose connections.
The house drain pipe is clogged. The washer pumps water out very fast, so a restricted pipe backs up. Source: Troubleshooting: Operation, p. 45
- Watch the drain pipe during draining. If water backs up out of it, check the drain hose installation and the drain for restrictions.

- Tie the drain hose to the inlet hose or standpipe so it cannot come out while draining.
- In a smaller drain pipe, insert the hose as far as its flange. In a larger pipe, insert it 1 to 2 inches past the flange.
