question for our retail guru

Dave

ok you would need to trace the other side of the resistor and see where it goes

Dave

[electrofix]

ok seems an interesting circuit

we need to see whats going on. seems like the board contains 2 circuits one to energise the other but cant be 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} as its difficult when your switching pics to try and trace tracks

for this circuit to work we need 240v ac to be rectified and smoothed to get about 320v DC there should be 400v caps on that board and you need to see if you have those voltages present

the output from the board on the grey wires shows 16v and 5v DC this has to be measured and to do this you need to find the negative which many be the next pin

Dave

please be careful as your dealing with dangerous voltages

[electrofix]

whats on the reverse of that board ?

Dave

[electrofix]

if it went with a bang it might well have welded the lock shut

also the manual release has to be held with one hand while opening the door with the other

if that does not work try thumping the casing close to the door lock as it sometimes jars it loose and allows it to open but it wont unlock it so you still have to use manual release method

Dave

[electrofix]

are you getting power to the board ?

I assume QER checked the board powered up so you should have 12v or os on the board on the chip outlet

dont know what R2 does so cant comment but it may be volts dc. a lot of the time there is a resistor that blows on boards when the lnk chips fail. i would ecpect this resistor to have 240v ac going to it unless its on the neutral side

Dave

[electrofix]

is it this one ?

if yes aswo list it but state 3 to 4 weeks delivery

Dave

[electrofix]

well it does not matter if you break the pump connector as long as the one on the wire is ok

you could try finding the barb and push it down but pushing a small screwdriver in between works ok for me. it is seldom the socket that gets damaged and the
plug on the pump is expendable if your changeing it

Dave

[electrofix]

there is a barb on the plug that locks into a slot the pump frame. just need to slide a small screwdriver in to ease it out

Dave

[electrofix]

it will be one of the elements with an earth fault most likely

Dave

[electrofix]

assume its not a washer dryer as the dryer ntc can cause problems

have you had a close look at the board. dont know if pump uses relay or triac

Dave

[electrofix]

have emailed you a doc on removal but not sure how much help it will be

Dave

[electrofix]

what do you mean by salt dispenser

do you mean water softner ?

Dave

[electrofix]

look here

Panasonic Direct

but you will need the rest of the modle no

Dave

[electrofix]

cant trace anything on this model at all
