E1 Error code - no leaks - new pump - new pc board in Dec. 09

\015 Could this be related to a fault in the new PC board that was replaced due to a call back on the previous one. We have replaced the pump there are no apparent leaks in this machine as indicated by the error code. This problem started a few weeks after the new pc board was fitted.\015

Answers :

\015\012The most common reason for an E1 error on an LD dishwasher (that does not have a leak, including directly under the dishwasher) is the drain hose between the dishwasher and the drain does not have a rise in it between the DW and the drain. Either install a proper AirGar valve or attach the hose to the bottom of the counter top so that it raises 30" between the DW and the drain. When that raise does not exist, the laws of physics tell you that you WILL have a siphoning effect from the DW into the drain, causing the LG to report error code "E1", which is true because of the water leaving the DW during all the wash and drain cycles.\015\012

E1 fault code Dishwasher runs for about 5 minutes. Water fills up at bottom of unit and then machine seems to pause then fault code E1 appears then water is pumped out from bottom of machine. There are no leaking pipes and drain is installed correctly. I installed a new wash pump and fault still appears.

My question is this: once the flood activation switch (F1 error code) has been activated due to water in the tray, will the switch self-set once the lower board area has dried sufficiently, or does it require a board replacement? I have found (I think), and will be correcting the leak, but wanted to make sure the water sensor is healthy or not.

SMEG STX dishwasher does not complete the wash cycle, stopping after 3 minutes on all cycles displaying error code E1. The machine seems to start with the usual whirring noise but then stops after 3 minutes without pumping in water. The machine is a few years old now but has needed 2 new control panels already although this does not appear to be the problem this time. Any suggestions? Thanks DW

I have a dishdrawer (2) and following the use of a dishwasher cleaner, the bottom drawer appears to have developed a blockage. It will not empty, gets to the pump out part of the cycle and shows the red error code F3, to which there is no reference in the trouble shooting guide. The top drawer has also developed minute leak, sufficient enough to leave dribble marks on the lower drawer and over time, a white deposit on the floor.

Dishwasher FDB4315LFC0 Error code ER uo Second time it has happened. First time, a repairman came and said I needed a new "vent assembly", but I asked if he could "un stick it," so he took it apart and fiddled with it, and it worked for about a month. Now the error code is back, and he warned that if it came back, I should have it replaced. I've only had this NEW machine 10 months -- this shouldn't happen, right? Any suggestions? Thanks.

We recently purchased a new pump for our frigidaire gld4355rf dishwasher. The old one started making grinding noises. When we moved the dishwasher it had leaked due to a failure of an interior seal. Our new pump is now making the same grinding noise but it is not constant. When my husband adjusted the pump by using his hand when he got into a certain position the noise stops. We keep the screens clean. Is there an issue with the pump in this model?

There are no error codes thrown on the control panel, but not sure there are error codes for this model - the manual doesn't mention any.

We have an LG dishwasher LD14AT1 P/No 3850ED3005R. It kept signalling an error to do with a leak- all hoses etc were checked, one relaced but no fault was found, so we had a repair man come out and he repalced the electronic board at a cost of $200.00. The error still kept signalling (by the dinging sound). It was then discovered that the appliance had rusted and there was in fact a leak in the base of the machine, not a fault in the electronics. The machine has just remained idle since. I belie

I have an LG dishwasher, model LDS 5811ww. The machine fills with water, then stops filling when the error code IE comes on. I have cleaned the inlet filter and the whole inside of the tub, by taking apart the sump filter. There is good water pressure filling the tank. When I turn off the power and restart any cycle, the pump will empty the tank, then begin filling the tank again...until it is stopped by the error code IE again coming on. The other thing I notice is the water level in the tub.
