Possible Causes

How to Fix / Troubleshooting
Safety First: Turn OFF power to the disposal and dishwasher. Do not run the dishwasher while the hose is disconnected.
- Step 1 – Observe during dishwasher drain: Run a short dishwasher cycle and watch the area around the dishwasher inlet on the disposal when it drains.
- Step 2 – Tighten clamp: If water seeps around the hose connection, tighten or replace the hose clamp.
- Step 3 – Inspect hose and nipple: Look for cracks in the plastic inlet nipple on the AmazonCommercial unit and splits in the hose. Replace damaged components.
- Step 4 – Re-test: Run another drain cycle to confirm the leak is resolved.
