Dishwasher refusing to run or running occasionally
My washer pump runs continually even though there is nothing in the sump and continues to run even when i open the door.
I suspect that the problem i have is the anti-flood switch since when i tilted the machine, a lot of water came out and it then did a whole cycle successfully on just two occasions before it refused to do more.
However, I cannot fathom how to take the thing apart! I can't take the sides off without first removing the top but there is no visible means of detatching it. Does it snap straight on or do I force it forward or back please?
Re: dishwasher refusing to run or running occasionally
Tip the machine side to side to relase the water,,, have a towl to hand,,,, this will relase the water which would of flooded your kitchen but the dishwasher cut off the water when the overswitch cut in,,, any way try and get all water out then retry

Continuous run of DW "drain pump" is common problem, with simple solution, and without "pulling" the DW!
Because the problem is likely a "stuck float riser assembly", a mechanical "glitch", from crud build up, I recommend trying one "might get lucky fix" first.
Look up above the door and remove (usually two) screws holding two metal "tabs" to bottom of wood counter. This should allow you to "rock" the unit a little. This might allow the float assembly to operate.
A. You have removed and cleaned the screens to the pump inlet and have manually added hot water which the pump removes but the pump just continues to run, even when you open the door? You should still be able to use controls to shut unit off. If not, you should be able to turn DW off at circuit breaker panel. Find and open the breaker any how, because "I'm sending you in!"
There are two sheet metal "plates" about 4 inches high, 24 inches wide below the door on Bosch (and others) dish washers. Remove both, usually they can just be carefully removed.
Lay with face on floor and use flashlight to look "up and into" the left bottom side of the DW. About a foot into the bottom left side of the unit look for a red or orange (usually) plastic rod about the size of a pencil rising vertically out of a thin plastic "tank". This is a "sump" of some sort (???) and the bottom of the rod is a "float". The top of the "pencil" activates a micro switch. Junk in "tank" or on micro switch stops rise of the rod which keeps pump running.
Carefully, manually lift the orange rod with a long wooden spoon. Several times. You should hear the micro switch click. Don't be sticking screwdrivers or anything metal in there. Even with the power off.
Turn breaker back on. This may solve most common problem in first five years for many brands of dish washers.
The reason the drain pump continously runs is because it is trying to remove any water too avoid any further flood as there is a flood in the base of the unit which activates the float switch and constantly activates the drain pump until the water has gone. Isolate the unit at the power switch and remove the bottom panel under the door panel. Dry up the water as best possible with a towel. Run the unit again and check for any water leaks. You may just have over sudded the unit with too much detergent. Only use 2 teaspoons of powder. To start with while testing don't use any detergent. Good luck
Water had accumulated in the sump - a plastic tray at the bottom of the dishwasher which catches any leaked water. This operates a float switch which makes the drain pump run all the time. The fix was to tilt the dishwasher backwards to drain away the water. It isn't filling up again, so I'm not sure where the water came from, but I'll keep an eye on it!
Intrrnal leak into base of appliance will make drain pump run constantly.
If appliance fills then dumps water with drain punp then keeps filling/draining sequence then the flow meter could de faulty.
