My dishwasher commences the cycle and fills perfectly but then errors with code E1 and empties itself. There are no leaks and has been working fine for months.
I did change the inlet hose some months back when it sprung a leak but has been working OK since. There was no error with the leak months back but a huge puddle of water on the floor.
What are the possible causes and steps to rectify?

Re: LG LD-A2T2 Dishwasher returns Error code E1
EI is an error to do with your drain. Check your drain hook up. You should have a loop out side the unit, it should be a minimum 40in in height, or put in a air break. What I believe is happening is your unit is siphoning out. Fix this and you will be able to stop washing the dishes by hand.

If you've checked everything, you will need to replace the impeller possibly.
Leakage error > Conditon: Excessive RPM of washing motor happened
during wash cycle due to water leakage.
Possible cause: Water leakage in hose connections,water is leaked by
damages. The motor water seal leakage of sump assembly. The height of
drain hose connection ( sink drain hose ) is not over 20". Impeller of
the washing pump is worn away.
The most common problem on an LG dishwasher when error code E1 is reported but there is no actual leak found is the problem of a natural syphon being created by improper installation of the dishwasher. Pretty easy to fix: Either add an Air Gap valve (available at any hardware store for almost free) or follow the drain hose from the dishwasher to the drain. Raise the hose and attach the hose to the up onto the bottom of the countertop. Adding that "rise" eliminates the possibility for the syphon effect to drain the dishwasher before the drain cycle begins.
If the hose ever fall back down, the problem will return immediately. Adding the Air Gap valve is harder but is far more permanent (and complies with construction codes that really should not be ignored.)
Please check at both ends of the drain hose and confirm that you do nit have a leak. Also, please confirm that water is not leaking directly under the dishwasher.
If you are certain that you do not have a real leak, check the impeller (under the mesh filter in the sump area beneath the lower dish rack) is not damaged and is firmly in place.
The E1 error code is a Leakage Error, detected by the motor spinning faster than it should if the unit is filled with water.
Please report back with what you find. Good Luck!
90% of the time you get an E1 error code is because the drain hose is not properly installed between the LG dishwasher and the drain. The hose should connect to an Air Gap valve (almost free at any hardware store) but in a pinch, raise the drain hose near the drain and attach the hose to the bottom of the counter top under the sink. Is should rise almost 30 inches between the dishwasher and the drain or the water WILL siphon out of the dishwasher as soon as the wash or rinse cycle begins (and take 5 minutes before the water gets low enough the cause the E1 error.
Well done by resolving this problem. The other way to avoid the siphoning problem through the drain hose is adding an air gap valve/connector (available at any hardware store). You can use it even if you don't have a garbage disposal in your kitchen sink. That will assure that you have the proper height of the drain hose.
Hope this helps!
E1 is a drain error. On the unit prior to mar 07 LG had a problem with wires breaking in the door. Turn off power supply, remove door panel and look for wires stuck in the insulation. Check continuity of the wires, if broken, splice and tape. Place insulation between black insulation and wires to prevent reoccurence.
