Count the number of flashes between each pause.i.e. 3 flashes pause 3 flashes pause etc. The number of flashes is the error code. In the meantime check that tap is fully on, check fill hose is not bent over & kinked. Take hose off tap & look if it has a filter which may be blocked. Try those & post back here with results & number of flashes.
