this machine keeps flashing up hf on the display i realise this is a fill fault and found filter and pressure chamber blocked. i advised customer to run a 90deg wash to flush the rest of the machine out. she did but 2 washes later it started flashing hf again is there anything else to look for when i go back? 😕
valve seens fine, flowmeter is clear it seems to do a boil wash ok but on other washes it seems to stop on the rinse with hf flashing just priced up the valve, flowmeter and pressure switch and they are about £30 each non returnable so if anyone has got any ideas would be grateful
