Check for objects stuck in drain hose or in pump on electric pump units. Ensure that drain hose meets drain height restrictions. Increase programmable drain error time if pump is working but not able to pump out quickly enough. Un-power to clear error. Restriction in the tub to pump hose, drain hose blockage in the pump.
