Possible Causes

Removed or worn rubber splash guard, Incorrect splash guard size for AmazonCommercial flange, High water flow directly into chamber, Partial drain restriction causing back-splash

How to Fix / Troubleshooting

Safety First: Keep hands clear of the opening while the unit is running. Turn OFF power before installing any parts.

  • Step 1 – Inspect splash guard: Check if the rubber splash guard at the sink opening is present and flexible. If it is torn, hardened, or missing, replace it with a compatible AmazonCommercial guard.
  • Step 2 – Adjust water flow: Reduce the faucet flow slightly so water does not blast directly into the chamber.
  • Step 3 – Check for drain restriction: If water backs up and then splashes, inspect and clean the P-trap and discharge piping.
  • Step 4 – Install correct guard: Ensure the replacement splash guard fits snugly into the sink flange and is designed for your specific AmazonCommercial model.
