Question about Dishwashers
E1 code - manual says pipe leak - I have checked no external leak present. Should I start stripping down unit looking for internal leak?
SOURCE: E1 error on LG - LD-4120M
E1 is a common error in the LG Dishwasher range and is usually caused by the failure of the circulation pump and/or the impeller.
The motor and impeller are a complete unit.
Often what happens is the impeller breaks on the motor shaft and doesn't spin, therefore doesn't pump water.
There is a pressure sensor which indicates the lack of pressure and shuts the machine down with the E1 error being displayed.
The lack of pressure can also be from a water leak (as the owners manual suggests) also a controller PCB fault may produce an E1 error, however, the pump problem is extremely common.
Unfortunately, I have had 5 pumps die in 4 years and my dishwasher is only used about 4 times a week.

This happens to my LG dishwasher every 6 months or so. It also makes a groaning sound as if the system is starved for water. The resolve the problem by removing the dishwasher and laying it over on it's right side. I then remove the two plastic assemblies that are on the left side and I remove them from the dishwasher (you will need a vice grips to remove the hose clamps from behind them, you will also need to remove the round circular water intake plastic disk that is on the inside of your dishwasher on the left hand side right in the middle of the left wall) and clean them. Once the water can run freely through these plastic parts you will get a good water flow and you should be fine. Until you have time to do this I recommend putting a few quarts of hot water into your dishwasher once you start to hear the groaning problem. This solution should be very easy for anyone who is comfortable doing their own oil change. Oh, and turn off the power supply first.

E1 means: Water Level in Drum lowering, this would usually mean there is a leak on one of the pipes. But from previous experiences it is more than likely (90%) that it is the Circulation pump. It will have to be replaced, as it is a common spare that has to be replaced on L.G Dishwashers (lifetime 12 - 18 Months usually) - Not overly expensive. Usually is about 20%-25% the price of a new Dishwasher. The Circulation pump is fitted to the sump.
See below a image of what a Circulation Pump looks like:
