Maintenance Tips
- Clean spray arms and nozzles daily; remove and flush to prevent clogging and ensure full spray coverage
- Remove and thoroughly clean the drain screen/scrap accumulator regularly to prevent food buildup and drainage issues
- Empty and rinse scrap tray frequently during operation, especially in heavy-use periods
- Inspect chemical feed lines and ensure detergent, rinse aid, and sanitizer levels are correct for consistent cleaning performance
- Run a daily cleaning cycle and wipe down interior surfaces to maintain hygiene and prevent residue buildup
- Check door seals, gaskets, and wash chamber for leaks or wear to avoid water loss and heat inefficiency
- Descale/de-lime periodically to prevent mineral buildup on heating elements and internal plumbing
- Verify water pressure (typically 15–65 PSI) and temperature (hot water supply required for proper operation) for optimal performance
- Inspect wash pump operation and spray arm rotation regularly to ensure proper mechanical function
- Keep exterior stainless steel clean and dry to maintain durability and sanitation standard
