Can anyone tell me my Nautilus dishwasher is displaying F4. It seems to make it to the last phase of washing then stops and beeps continually.

Thanks, I think you are right, when I open the door the is no heat at all. Is it a major effort to replace the element, as it appears difficult.
Thanks again for your help

F4 means it has failed to heat the water in the allowed time. May be a faulty heater element, faulty temperature sensor, overheat temperature thermostat cut out or a faulty control board. At the point when F4 appears, open the door & feel if there is any heat in the cabinet. If yes, then rule out element & thermostat cutout & look at temperature sensor fault or control board. If no heat then more likely to be element or thermostat
