BOSCH SHV4313 Dishwasher pump will not cut-out

[IanSh]

The pump on my BOSCH SHV4313 Dishwasher will not cut-out. The control panel indicator is showing “End” but the pump just keeps on going.

I assume that this is either a fault with the control panel or possibly a sensor? I have disconnected the control panel and reassembled and the problem cleared much to my amazement (see also P.S. below). However, this could have be coincidental as the problem reoccurred after only two days. I have take the control panel apart again (down to the PCB) and there are no obvious signs of damage (the relays rattle somewhat but I guess this is normal?). On reassembly the pump still keeps going.

So before looking at getting the control panel checked out, could it be a sensor? If so, can anyone advise what sensors are connected with the pump circuitry and where they are located? Is there an easy way of determining whether it is the control panel or a sensor?
I don’t want to spend too much on a repair as the machine is just over 5 years old.

P.S. Just before the problem occurred for the first time we used a different Salt and for some reason nearly all the salt was used in one wash. This I guess could have caused a problem with a sensor. When I removed the control panel for the first time, I also added hot water in the theory that this might clear any sensors – so this may have helped. However, repeating this exercise has not helped a second time. Any indicators as to the likely cause would be very much appreciated.

Hi Ian
With the appliance unplugged :plug: have you checked the base (under the tank) for water thus activating the float?. Remove lid and the sides to gain access.

No I haven’t. With the pump running all you hear is the rushing of air so I assume there is no water left. If the float is reasonably accesiible? –then I will check tomorrow that it is not stuck.

Many thanks,

Ian.

hanks. Absolutely right. The base unit was swimming in water. Once removed everything was fine. My conclusion was that when adding salt the bottom ring was loosened causing the water leak. After tightening there seems to be no further leak. A cheap fix (with the exception of time)!!

greetings. new here, though not exactly new to fixing stuff- mostly I am a broadcast engineer & musician but I have had a few white goods in bits over the years too.
this bosch 4313 at my girlfriend’s place worked fine the other day, then the g/f loaded it again & it wouldn’t power up. I checked the fuse- open circuit. I replaced the fuse.
my rule regarding fuses is to keep replacing them until the appliance, whatever it is, gives forth a clue as to what is ailing it.
this appliance let forth one of the loudest bangs I have ever heard. no smoke, but just the faintest whiff of something that conducted for a few mains-cycles & then stopped conducting very abruptly.
oh, & the main start/stop switch was in it’s “off” position at this point. I realise that this deosn’t necessarily mean the machine was really off.

when I have a little more time, I will dismantle the b*gger & see if there are any visual clues as to how expensive this may prove. in the meantime, anyone care to share previous experiences of this nature? am I likely to be into a new element, controller pcb or pump? or could I have just fried a stray rodent? 🙂

My rule regarding music is to turn on the radio/CD player and listen to the experts.

Its a pity that you rule on fuses isn’t the same. One sure fire way to turn small electrical/electronic problems into major disasters, total right offs or even fires is to do as you have done. It may be too late for this machine but I strongly advise you to revise your methods before you do some serious damage. 😯
