2. How can I prevent recurring GE washer errors, such as UE or LF?
To prevent errors like UE (Unbalanced Load) or LF (Long Fill), ensure that you balance laundry loads properly and avoid overloading or unevenly distributing clothes in the drum. Regularly inspect the washer’s hoses and valves, cleaning the inlet screens to remove any mineral deposits and maintain proper water flow. Routine maintenance, such as cleaning the drain pump filter and checking for blockages, is also essential for preventing these errors.
3. Why does Alarm 2295 occur, and how can I avoid it?
Alarm 2295 occurs due to issues such as mechanical obstructions, servo motor malfunctions, overloading, or programming errors. To avoid this error, conduct regular maintenance to inspect for wear and tear, and ensure operators are trained to configure G-code correctly and manage tooling loads appropriately. Keeping the machine’s firmware updated also helps prevent software glitches that may trigger this alarm.
