Drainage

more then likely that your pump or the drain hose has a slight blockedge you can kill 2 birds with 1stone here you can get rid of the water and see if the pipe is blocked by taking the pipe and placing it low to the ground into a bucket if the water comes out slow then you will have a blockedge and your pump will be ok now make sure you pull the plug out pull the asher out now tip it backwards just enough so you can see the pump at the back undue the clip which holds the pipe onto your pump now there will be some water that will leak out once pipe is free you can pure water down it by putting it onto the tap if it comes out fast then the block is in the pump
