Possible Causes

Drain hose too low, Drain hose sealed in standpipe, Incorrect installation height, Standpipe configuration causing back-siphon

How to Fix / Troubleshooting

Safety first: Disconnect power before moving the appliance.

Steps:

  • Verify installation height: Ensure the drain hose height meets Café specifications (typically 30–96 inches above floor).
  • Provide air gap: Make sure the drain hose is not taped or sealed tightly into the standpipe. There must be an air gap to prevent siphoning.
  • Secure hose: Use the supplied U-shaped guide to secure the hose at the correct height without kinks.

When to call a technician: If installation is correct and code 23 persists, internal pressure sensing or control logic may be at fault and should be checked by a technician.
