I have the same problem. First fault was caused by poor workmanship on the assembly of the PCB. There is a relay (the largest component on the board) which was badly soldered and caused some arcing resulting in solder splattered around the plastic casing and a lost electrical connection. This relay switches the mains voltage on to the heater i.e. 240V around 8.5A for a 2kW heater. (26 ohms suggests a 2215W heater for the case mentioned). Re-soldering this connection solved the problem for about a year. Now the dishwasher is showing the same problem. I have tested the relay and it is operational, but does not seem to be turning on during a wash cycle. A new board costs around £100. Zanussi will not even provide the technical details to allow a home fix. I will post my finding if I get to the bottom of this problem. It may be to do with electrical temperature sensor. My hunch is the controlling PCB is cheaply made and will not last a reasonable lifetime. A dishwasher is in itself a very simple piece of equipment with only a few valves, a pump and a heater so should not give problems in its first five years of life subject to normal usage. I will not consider purchasing any Zanussi appliances in the future.

c3 means that the temperature of the water inside the tank is higher than 60 degrees celcious.may be you have already connect the dishwasher with to much hot water or the rele inside the pcb is stuck.

Tips for a great answer:
Thank you for your inquiry, Elizabeth!
I see that your Frigidaire dishwasher is displaying an error code of "UL" and you would like to know what it means. A "UL" error code means that your dishwasher is in relay test mode. You should be able to clear out the error code by pressing cancel and holding down the hi-temp button. If that does not clear out your error code I would suggest performing a reset on your dishwasher and you can do that by flipping the household circuit breaker off for at least ten minutes. Hopefully this information is helpful. -Matt
