Hi,
Although a few modern washing machines can operate with the drain pipe at any height, most machines will drain the water as soon as the drain pipe is placed below the machine water level.
The simplest solution for your problem would be to ask somebody with some handy man skills or hire a plumber to add a 2 inch PVC pipe to your drainage pipe which extends to a point behind your washing machine & then points upwards, making sure it is long enough to be at a higher point than your machines fullest water level.
This should be a relatively inexpensive alteration & will ensure that water does not drain unless the machine is on its drain cycle.
Please let me know if you need any further assistance.
Best wishes,
Graeme
Siphoning occurs when the end of the drain hose is lower than the level of the water inside the washing machine. It's exactly the same principal as siphoning beer out of a barrel into bottles or siphoning petrol from a tank. If the end of the drain hose is very low, then water can siphon out as soon as it enters the washing machine. If it's just slightly lower than it should be, then siphoning is usually triggered when the washing machine first pumps water out or even just occasionally.
This fault most often occurs when the washing machine has been moved out for cleaning or relocated in a new house etc. It can also occur if a drain hoses stand pipe isn't properly secured to the wall and falls over at an angle.
The drain hose should also not be pushed down too far down into the waste water pipe, which can cause siphoning just the same as if the stand pipe is too low. It needs to go just far enough in to prevent it falling out but it will fall out if not secured properly with a crook or tape. If the stand pipe that the drain hose is being pushed into is too low, then it may need raising. It could have fallen through the floor boards in which case you can gently raise it and secure it to the wall with proper brackets. If it was just installed too short, you can add a small extension piece.

Hi from retired Englishman in SW France,
As long as the drain pipe 'outlet' is above the level of the water in the tub it should be fine but basically the higher the better. I am guessing from what you are saying but you may have to have the u-bend/drain outlet also moved closer to the machine so it is 'as-it-was' before you moved the washer.
Hope this helps. I've posted as 'clarification' ;-0)
