Bush BFSNB12W – F5 Error

[mikedmc16]

Hi,

I have a Bush BFSNB12W dishwasher that is giving up the F5 error.

I’ve googled and youtubed to my hearts content. It seems to be either a draining issue or a insufficient intake issue.

The machine drains, and fills up but 2 minutes in after it drains water away the F5 error springs up. It seems when it is supposed to fill up again.

I have undone all pipes and checked, water is flowing through the pipes to the machine fine and also draining away fine.

As it is filling and draining in the first couple of minutes, and not intermittent I am at a loss but it has lead me to the inlet valve?

Is this the most likely possibility? Anything else I could look at first?

Thank you.

somewhere there is a pressure switch

this senses water level. its either blocked up ( dont blow into switch directly)

or there is no water going in to sense

check for water flow, check switch and make sure its not blocked. check wiring from switch to board

or the board is faulty

I will find it today and check, thank you.

How can I check switch is working, once I’ve confirmed water flow and not blocked?

no easy way. with the later switches you can destroy them if you blow into it so the only way is to swop them out

your lucky in one respect as this unit is a known manufacturer , most Bush stuff is chinese junk with little access to spares or information

Ok. So if water flow and not blocked, best to simply change the switch. If that doesn’t work it’s the board and time to simply get a new dishwasher.

ver likely

the pressure is fed to the swich via an air chamber, make sure thats not blocked

if you get me the long serial number will try to find correct switch

This I assume is the SN but entering into Google gets no response.

ok now i have the correct machine

your has got a flow meter that measures water coming in

check wiring to this ( have had mice eat the cables)

if wiring ok it should be either this part or the board

cant promise i am right as you can imagine but changed lots of flow meters

Will check it once home today.

Out of curiosity, as you know your Dishwashers and these Bush are full of chinese junk, what is a recommended Dishwasher make / model?

[electrofix]

most appliances contain chinese components

you dishwasher is made by a turkish manufacturer called Vestel
