TLDR
On your UC Series unit, the "Activated carbon filter used up" message indicates that the filter has reached its service life and requires replacement. To resolve this, you must install a new activated carbon filter and then reset the filter counter through the machine's control panel to clear the notification.
Technical Details
Repair Steps:
- Safety First: Before beginning any maintenance, always disconnect the Winterhalter UC Series unit from its main power supply to prevent electrical hazards. Ensure the machine has cooled down if it was recently in use.
- Locate the Activated Carbon Filter: Depending on the specific UC Series model and installation, the activated carbon filter is typically located externally, often mounted on the wall or stand near the dishwasher’s water inlet connection. Consult your Winterhalter UC Series operating manual for the precise location.
- Isolate Water Supply: Close the water inlet shut-off valve to the filter housing to prevent water flow during the replacement process.
- Replace the Activated Carbon Filter Cartridge: Carefully open the filter housing. Be prepared for some residual water. Remove the old activated carbon filter cartridge and dispose of it properly. Insert the new, genuine Winterhalter activated carbon filter cartridge into the housing, ensuring it is seated correctly according to the manufacturer’s instructions.
- Secure and Restore Water/Power: Close the filter housing securely, ensuring no leaks. Slowly open the water inlet shut-off valve, checking for any leaks around the filter housing. Reconnect the UC Series unit to its main power supply.
- Reset the Activated Carbon Counter: Navigate through the UC Series’ control panel menu to the ‘Service’ or ‘Settings’ section. Locate the option for ‘Activated Carbon Filter Counter’ or similar. Follow the on-screen prompts to reset the counter to zero. This action clears the “Activated carbon filter used up” message.
- Verify Operation: Run a short cycle on the dishwasher to ensure proper water flow and confirm that the filter warning message has cleared. Check for any new leaks around the filter housing.
Common Questions:
Q: What is the purpose of the activated carbon filter in my Winterhalter UC Series dishwasher?
A: The activated carbon filter is designed to remove chlorine, odors, and unpleasant tastes from the incoming water supply. This helps ensure optimal washing results, especially for glassware, and extends the life of internal components by protecting them from chlorine corrosion.
Q: How frequently should I replace the activated carbon filter on my UC Series unit?
A: The replacement frequency depends on your water quality, machine usage, and the specific filter’s capacity. Your UC Series unit monitors its usage and will display the “Activated carbon filter used up” message when it’s time for replacement, typically indicating it has reached its rated capacity.
Q: Can I continue to use my Winterhalter UC Series if the activated carbon filter message appears and I haven’t changed it yet?
A: While the machine may continue to operate, it is highly recommended to replace the filter promptly. Delaying replacement will compromise water quality, potentially leading to poorer wash results (e.g., cloudy glassware, lingering odors) and may not adequately protect the machine’s internal components from chlorine.
