Identifying Drain Pump Problems
Listen for unusual sounds and check if water is pooling at the bottom after a cycle.
Solution
If you suspect a drain pump issue, it may require professional assistance to examine, repair, or replace the pump.
7. Faulty Door Seal
The door seal keeps water inside the dishwasher during operation. If the seal is damaged, water may escape, causing poor rinsing performance.
Identifying Door Seal Issues
Inspecting the seal for wear and tear is essential. Signs of damage may include cracking or distortion.
Solution
To fix a worn seal:
1. Clean the seal with a damp cloth to remove debris.
2. If the seal is damaged, consider purchasing a replacement and installing it according to the manufacturer’s instructions.
8. Hard Water Buildup
If you live in an area with hard water, mineral buildup can occur within your dishwasher, leading to poor rinsing performance.
Identifying Hard Water Issues
Look for white, chalky deposits on your dishes or inside your dishwasher.
Solution
To combat hard water:
– Use a descaling agent designed for dishwashers to remove mineral buildup.
– Consider installing a water softener to prevent future issues.
