Hello..I am using fully automatic top load washing machine Panasonic NA-F70B2 …yesterday it suddenly had a blast after few minutes of cycle started…I saw lil smoke and smell coming out of it…i call a repairman…he replaced the inlet valve and the fuse…then i turned it on and the water started immediately even before i adjusted any program…and won’t stop while overflowing… then he replaced the pressure switch… but the problem remains..he is saying the main control panel is gone…but everything else is working fine other than the water supply problem…can it really be the control panel?
Sounds to me like the water level switch has failed. Take a look at the main control board and other components to see if you can any visual evidence of where the smoke was coming from (burnt insulation), and let us know.
@msuns, check the wiring to the connector. Follow the wiring guide. Also, check the connector with a multimeter. It sounds like it continuously excites the solenoid on the water inlet valve. You need to set your multimeter to the voltage settings that are appropriate for your household (whatever country this may be:-)This could be by shorted wires as well as a failed control panel. If it is the control panel than you should not have anything at the connector end. That failure would be most evident in the control panel. Do also check the water level sensor to ensure that it does not send a continuous signal.
The valve is a solenoid , basically a coil of wire with a rod or actuator in this case. The coil on the solenoid is cooked. That is how the valve works. If it is a new valve (solenoid valve) and is still not operating then the guy is right . The part of the board that controls the solenoid is cooked. An electronics tech worth his salt could repair it or you could be lucky and the board has a fuse cooked on it. ( usually 120v items are fused) Does the water still run without the run on ? The actuator could be stuck as well , which is why the fuse blew and still doesn’t work. See what voltage if any is going to the valve? I would guess it’s something simple, but bad luck w a board is always possible . Keep posting I will keep an eye out for ya and let us know
