Dishwasher trips the house mains

Did water get into the control panel?
Some youtube videos that may help.

Looks like the pump motor is drawing lot of current and tripping the circuit breaker. Need to check if there is any water inside it. Or simply the capacitor is leaky and causes motor to draw current.

See this part.

Had a look in the user manual for your dishwasher.http://downloadcenter.samsung.com/content/UM/201211/20121101114232459/DW7933LRASR-00141A-02.pdf

Page 26 shows blinking Heavy light means there is leakage in the dishwasher. Most likely there is water in the base under the drain sump which could cause the flood switch to trip. Turn mains power to dishwasher off. Pull it out from under kitchen bench without breaking the hoses. Put some towels on the floor and turn dishwasher back and forth on incline to get water out. Wait a little and turn on. If no difference then you need to dry the base and find the source of the leak. More likely the door seal.

Not sure what the actual model number is but usually the F1 error with Fisher and Paykel dishwasher means water has entered the flood switch located at the base. This could be due to leaky hoses or water leaking through the door or lid seal. Wait for a day or two until the water evaporates and try again. Otherwise you will have to dry out the flood switch and then try again. Location of flood switch will depend on your model. For double drawer dishwasher you will have to take the bottom drawer out from the housing and the switch is on the floor of housing. But make sure you take the mains power chord out before touching the insides of dishwasher. Will also need to find the cause of the leak. Other reason for F1 could be loss of power to top dishdrawer if you have double drawer. But in that case the top drawer will have no lights on. The power board is located on the base of housing under bottom drawer. Once again do not touch inside of dishwasher without shutting off mains power.

This is most likely the cause of the problem. There is a short in the device.

check the flood control switch and inlet valve..be sure the float is on under the bottom rack

Hello. I can help you. Since you already checked out the power, skip that step and look at the latch.

If your dishwasher doesn't work at all, check these:

Power from the house
Door switch
Wiring
Timer or selector switch
Power from the house Is there power getting to the dishwasher? This can be difficult to test, because dishwashers are usually wired directly to an electrical circuit, rather than plugged into the wall. But at least check for a blown fuse or a tripped circuit breaker.

Door switch The door switch is important because, if it's defective, the dishwasher won't work at all. To reach it, you need to remove the control panel cover, or sometimes the interior liner of the door. If it's defective, you need to completely replace it.

Wiring Often the main wiring connection from the house, at the dishwasher, burns and breaks the connection. If that's the problem, the wires must be repaired/replaced as necessary. If that's not the problem, check the wiring to the door switch, the wiring between the door and the lower part of the dishwasher, and the wiring to the timer. Repair any broken, burned, brittle, or defective wiring, using the proper appliance-grade wire and connectors.

Timer or selector switch Although it's uncommon, the timer or the selector switch may be defective. If so, you need to replace the defective part, because neither of these can be repaired.

Is it possible that water has gotten inside the controls that could have caused the flashing lights? Kind of like spilling water on a calculator, everything seems to go haywire.

Hello,

My dishwasher a diplomat 12 program (hja8640) was doing exactly the same where every now and again when turned on at the plug it would trip. After engineers coming out several times and failing to fix it, they condemed it. New one was supplied, however did exactly the same thing. The electrician came back, checked the RCD power breaker and this was fine. It was then discovered that some dishwashers and washing machines send out a lot of earth leakage, combine this with other appliances on in the house can be enough to trip.

Soloution. The electrician removed the kitchen circut from the RCD breaker and intalled another breaker RCD just for the kitcehn loop, this therefore means that the kitchen has a seperate trip from the rest of the house, and touch wood, has solved the problem. This mind you has taken about three months to work out so i hope it saves you some time.

Always use a fully qualified electrician though.

Thanks.

remove the door skin dont forget the two screws under the door in the middle,the control panel will lift off remove the power board(unclicks)remove the plastic case and see if its blown.But first also remove the lower kick plate at the front and check that you have power to the main terminal block.but most likley the main board,somtimes insects get into them.hope this helps.Ian ps did you push the main switch in top left i have had a lot of customers forget.
