Troubleshooting Guide

Provides guidance for diagnosing and resolving common issues.

General Troubleshooting

• WARNING: Procedures are for qualified service technicians only. Turn off power when replacing components.
• Scald and Burn Hazard: Keep body parts clear of hot surfaces.
• IMPORTANT: When replacing the UPM, always check valve coils for shorts and replace if necessary.
• Troubleshooting Guidelines: Consult ERROR CODES for display messages. Ensure the brewer is level. Use this guide with the appropriate ELECTRICAL SCHEMATIC.
• Valve Test Procedure: Use a multimeter to measure valve coil resistance. Less than 100 ohms indicates a shorted coil requiring replacement. Test for open coils by reconnecting and using diagnostics.

Common Issues and Solutions

• Water Not Hot Enough: Check temperature setting. If correct, replace temperature sensor.
• Water Heats More Slowly: Check heating element power and continuity. If no power, trace circuit. If power is supplied but no heat, check SSRs.
• Dispenser Overflows During Brewing: Check UCM brew/bypass/dilution levels. Check for missing spray head. Ensure dispenser is empty before brewing.
• No Power - Display Not Lit: Check circuit breaker, power plug connection, main toggle switch, wire connections, chassis ground. Check low voltage input to UCM. Trace power loss if UPM is suspect. Check thermostat reset switch.
• Brewer Does Not Start When Brew Button is Pressed: If "Brewing" displays, check UPM-valve wiring. If "Brewing" does not display, check UCM or UPM.
• Sensor Error Message: Indicates an open circuit in the temperature sensor system. Check sensor resistance; replace sensor if open (>200 kΩ). If resistance is normal, check wiring or replace UPM. Reset error by cycling power.
• Water Tank Overfills: If water continues to flow when OFF, replace inlet valve. If water stops when OFF but flows when ON, check water probe connection. If probe connection is OK but tank still overfills, check tank ground and orange wire continuity, or replace UPM.
• Water Tank Does Not Fill: Check water supply and inlet valve for plugs. Check inlet valve terminals for power. If powered but no flow, replace inlet valve. If no power to inlet valve, check UPM wiring. If wiring OK but no power to valve, check water probe wire. If tank fills when probe wire is removed, replace probe; otherwise, replace UPM.
• Coffee/Tea Too Strong: Refer to "Dispenser Not Filled To Normal Level During Brewing".
• Dispenser Not Filled To Normal Level During Brewing: Check UCM brew/bypass/dilution levels. Verify water supply flow rate and pressure meet specifications. Ensure spray head is clean, correctly aligned, and tubing is not kinked. Run brew cycle to check dump/bypass/dilution valves for proper operation and flow. Check for obstructions or replace faulty valves.
• Dispenser Overflows All Of The Time: Check if water flows from spray head, bypass, or dilution spout when OFF. Replace stuck-open valves. If valves operate correctly with ON/OFF switch, replace UPM.
• No Water/Tea Flows From Brewer During Brewing: Check water supply. If tank is full, hot, and powered, but no flow during brew, suspect a bad UPM. Check UPM power output to dump/bypass/dilution valves.
• Low Water Flow Warning: See Water Level Error Message.
• Water Level Error Message: Occurs when inlet valve solenoid is on too long. Clear error after correcting malfunction. Check flow rate, water pressure, and inlet valve/tubing for blockages. Check water probe wire. Cycle power and check power to inlet valve. If powered but no flow, replace inlet valve. If no power to inlet valve, check UPM wiring; if wiring OK, replace UPM.
• "Internal Error 1" Message: Check wiring harness between UPM and UCM.
• "Internal Error 2" Message: UPM and UCM settings mismatch; firmware update needed. See PROGRAMMING GUIDE.
