This one intermittent. pump runs but will not lift water intermittently to spigot on u bend. repaced pump removed non return flap and all hoses off and clear. the only thing i can see is that the pipe that runs out the wall is the same height as spigot inlet. Could it be trying to push the water out of bend as well?
Cust swears no problem draining with old dishwasher. However this one is chinese…
