Technical Details

Repair Steps:

  1. Verify Detergent Canister: Check if the detergent canister is empty. If so, replace it with a new, full canister of the specified detergent. Ensure the correct type of detergent is used for your machine.
  2. Inspect Dosing Hose: Carefully examine the detergent dosing hose for any kinks, blockages, or signs of breakage. Straighten any kinks and clear any visible obstructions. If the hose is damaged, it should be replaced by a qualified technician.
  3. Prime the Dosing Device: The dosing device may need to be primed to remove any air pockets and ensure proper flow. Refer to your WINTERHALTER UC Series operation manual (typically page 47) for specific instructions on how to prime the detergent dosing device.
  4. Adjust Detergent Dosing Amount: Incorrect dosing settings can lead to insufficient detergent. Access the machine’s settings (refer to page 17 of your manual) and adjust the detergent dosing amount according to the manufacturer’s specifications for your specific detergent and water conditions.

Common Questions:

Q: Why are my wash items not coming out clean on my Winterhalter UC Series?

A: The most common reason for unclean wash items is an issue with detergent dosing, such as an empty canister, a blocked or kinked dosing hose, or incorrect detergent dosing settings in the machine’s program.

Q: How do I prime the detergent dosing device?

A: Priming the dosing device typically involves initiating a manual prime cycle through the machine’s control panel or physically bleeding air from the system. Consult page 47 of your Winterhalter UC Series operation manual for the exact procedure.

Q: What should I do if I suspect the detergent dosing hose is blocked?

A: First, turn off the machine. Visually inspect the hose for any external kinks or damage. If a blockage is suspected internally, you might try gently squeezing the hose to dislodge it. If the issue persists, a technician may need to disconnect and clear the hose or replace it.
