Poor cleaning performance

"1. Water temperature below requirements (below 120℉ (49℃)), affecting cleaning performance;
2. Insufficient water pressure in the inlet pipe (below 0.04 MPa), resulting in low water flow;
3. Dishes are arranged too densely, obstructing water spray;
4. Filter holes are clogged, affecting water circulation;
5. Drain pipe trap height is insufficient, causing water backflow;"
