We get AL99 all the time. Hotpoint couldn't really answer the question but told us to switch the unit off for 30 secs which should clear the problem. It doesn't! Today we got AL03 which Hotpoint advised is either a clogged filter (already checked), a blocked or kinked outlet hose (already checked) or the pump (guessed it might be). As there appears to be no physical attempt by the machine to pump the water out of the unit I'm guessing it is the pump and not the programmer at fault and will now shop around and fit a new pump myself.
