Rinse aid is not dispensing; dishes have water spots and the rinse aid level never seems to drop.

Safety first: No high-voltage work is required for basic checks; disconnect power if removing the inner door panel.

Step-by-step checks:

• Verify fill: Open the rinse aid cap and ensure the reservoir is actually filled.
• Clean cap and outlet: Remove any dried rinse aid around the cap and outlet using warm water.
• Cycle observation: Over several cycles, mark the rinse aid level to see if it drops. If not, the dispenser may be stuck.
• Door panel removal: If comfortable, remove the inner door to access the dispenser and check for broken levers or disconnected wiring.
• Replace dispenser: If mechanical or electrical failure is found, replace the rinse aid/dispenser assembly.

Warning: Avoid overfilling rinse aid; spills can cause excessive suds and streaking.
