Re: blowing the electrics

Urgent - do not use this again until an electrician has viewed it. There is a short somewhere, which is why it is blowing the electrics, and since we are talking water here, you need to unplug it and get it checked. A frayed cable may be touching a part ot the steel frame, which will make the whole unit live, which can kill. This is why it is blowing the electrics.No quickfixes here, get an expert.

Re: blowing the electrics

You need to get to the drain hose (always a bit fiddly with a built-in model). Look at how it is routed (the position of the highest point is important for later), then extract it from its connection to the mains drainage, and use it to empty the machine into a shallow container placed lower than the dishwasher. As soon as the whole hose gets below the water level in the machine, it will start to drain. Because shallow containers tend to fill quickly and are then hard to move away, you may want to take several bites at this: Every time you want it to stop, lift the free end of the hose above the water level and secure it there so it doesn't fall off when your back is turned. When the machine is empty, put the hose back where you got it from, paying particular attention to where the highest point in the hose goes. In terms of what's blowing the electrics: Unless you know the machine has suffered physical damage from some external mishap, the usual culprit is pinhole corrosion in the jacket of the heating element letting water in to compromise the insulation. To prove the fault: Disconnect electrical power. Find the electrical connections to the element and pull off the two that go to insulated spade terminals (the one that goes straight to the body is the earth, and should be left on). Tie the bare wire ends off with insulating tape so they don't touch anything they shouldn't. Reconnect the power and try to run a cycle. Even though the cycle is unlikely to complete properly in this condition, you will know the original fault lay with the element if the machine manages not to blow the electrics any more. New elements are not usually difficult to fit - expect to pay about £40 for the one for your machine. A.

Motor keeps running. Water heats fine. Help

One of the reasons for motor not draining during normal cycle is the check valve is stuck. It is meant to return to normal during drain cycle but close during wash. I think the cancel is resetting it and letting water out.

Are you replacing the wires along with the fuse? It is important to change the wires too as they are usually the cause for the fuse blowing. Be sure and get the fuse kit that includes the wires.

Is your water too hot? Hot water is fine but too hot of water can cause the fuse to blow over time. The temp should be somewhere around 120 F. Anything over 130 F is way too hot. I personally don't use a long high steam final rinse or high heat because over time the steam and cause the electronics to short as steam and moisture can get into the keyboard and inside panel.

F1 code indicates an overfill condition which may cause when dishwasher can’t pump out dirty water due to a plugged drain hose.
open dishwasher fully ,dry up as much water as possible then put a hair dryer on hot and direct into the back of the cabinet you will see a grey plastic cover on the bottom floor this is the sensor run on full for about 5 - 10 minutes making sure the heat go into that area. Also don’t overheat your hair dryer, when finished close the dishwasher shut and start your normal cycle.

Thanks for contacting

Dishwasher is draining during the wash cycle, but leaves water in the bottom at the end of the wash. What could be the problem?

Hello Ellsaesser,

Dishwashers typically leave water in the drain system exitting the pan but not a lot of water. If yours does then make sure you clean the drain screen ( normally located in or around the drain tube exitting the pan of the dishwasher..) If after cleaning that and after a normal wash cycle you continue to have significant volumes of water in the pan, the pump, lines leading to and from that pump may be restricting flow or damaged.. Those are a few of the normal culprets for why there is a lot of water in the pan of dishwashers after a cycle.. Hope that helps you identify the problem and resolve it,..,

Make sure the sprayer arm is turning freely, check for something stuck in the base of the sprayer arm (food or utinsel) preventing it from turning.

Dishwasher not spraying

It could be a motor or a pump issue. The dishwasher has a motor that attached to a pump which forces the water up into the sprayer arms and during the drain cycle, it pushes the water out of the dishwasher. The motor (and pump) located beneath the dishwasher. Good luck!
