I called to above the fault code is from left to right 3 neons flash then 4 th intermittedly. Appliance pumps out then circulating motor cuts in at the same time as fill. Water cuts off but bottom spray arm barely turns and water is only getting half way up top spray arm tube. Its as if there isnt enough water OR PUMP IS KAPOOT. Ive had pipes off and checked for blockages, pump and heater ok. Any ideas.
