Drain System Maintenance
| Maintenance Task | Frequency | Procedure |
|---|---|---|
| Clean drain filter | Every 3 months | Access front filter panel, remove and clean filter under running water |
| Inspect drain hose | Every 6 months | Check for kinks, cracks, or obstructions in drain hose |
| Check drain pump | Annually | Listen for unusual noises, check for proper water flow |
| Clean drain standpipe | Every 12 months | Ensure standpipe is clear of debris and buildup |
| Inspect high loop | Every 6 months | Verify drain hose high loop is properly positioned |
| Test drain function | Monthly | Run empty drain cycle to verify proper operation |
