    Thanks, worked great. The wires in my machine were red, white and black but easy enough to trace back to the tray sensor.

I had the save problem with my 3400 series.
The first time i was able to let it dry and it worked alright (48 hours).
The second time even this did not work.
If you remove the screws on the bottom of the unit. There are about 10 and pull it down, you will see the sealer assembly and a small circuit board in the middle.
Trace the wires from the drip tray, there are three of them, red white and brown, to the small white plastic JST connector on the small circuit board. Pull said connector gently to disconnect it.
The unit will function perfectly now, although it will no longer have a drip tray sensor of any sort it will function every time all the time.
All in all this took me about 10 minutes.
Thanks!

    I have a 3880 model and the solution Alex suggested worked after everything else failled. slight differences on the V3880 were that my wires were red, white and black ( and very hard to reach behind tubes and other wires) and we only had 8 screws on the bottom of the unit. If u have my model, you'll need a long needle nose pliers to get at the JST connector. Thanks, Alex!

See the little metal contacts on the left end of the tray. Lift tray out, cut a strip of cellophane tape and wrap it around the end of the tray covering the contacts and put the tray back in. You will have to push a little harder to get the tray in due to the tape. The contacts turn that light on and the tape insulates the tray contacts from the contacts down in the Foodsaver. Did it last night, works like a charm. Remove tape if you want to.

I also unscrewed the screws from the bottom and cut the white wire that leads to the underside of the tray sensor - about midway on this wire so it could be easily reconnected someday...? But that solved the light on problem. Now it works great., but indeed - I must certainly check before I use the sealer each time that the tray is clean and dry.

Went with Alex's solution, eight screws around the outside base and two screws on the cord winder. Traced wires back to board, medical forceps used to pull white plug from board, ten screws later I'm up and running. Thanks Alex....

I pulled out the cellophane tape so I could try this method after cleaning and drying didn't work. I noticed when I looked at the contacts that they were slightly corroded so I used the car battery cleaning method. I poured club soda on the contacts and scrubbed them with a clean cloth. Left it to dry for about 10 minutes and it worked!

Mine is a 3840. Tried cleaning, drying with a hairdryer, leaving for a few days, insulating the contacts. Nothing worked so went with Alex's suggestion to disconnect the Tray Full Sensor on the circuit board. It worked immediately! I am not at all handy but after I traced the wires (which were black, red and white in my case) to the connector in the middle of the circuit board it was fairly easy to unplug the connector by giving a sharp tug on the wire. The longest part was dealing with the screws. Do not be afraid to try this!

When excess liquid fills the Drip Tray, the unit will turn off and the Tray Full Indicator light will activate. To resume normal operation, open Appliance Door, press two release buttons, rotate appliance away from you, and allow appliance to rest on the counter. Then empty Drip Tray, clean it and place it back in the appliance.

Bag shows full when it's empty. No clog in the hose, but when I start to vacuum, the bag-full indicates FULL, even though it's a new bag.


See if there are any sponge filters that might be clogged. They're usually between the bag and the air flow going to the motor.

MY FOOD SAVER HAS BEGUN NOT VACUUMING. IT SEALS BUT DOES NOT GET THE AIR OUT LIKE IT USE TO


Does it hum as though it's vacuuming? If not, it's probably broken - the vacuum pump is out. It's cheaper to get a new one than attempt to get the old one fixed. If it hums, then replace any hoses you find or the foam around the drip tray.

I am using a hoover ultra steam cleaner but the red ball keeps coming to the top . I assume this indicates it is full and ready to empty however it is still empty . The red ball will not stay down in order...



Thankyou,

The redball indicates that it is full, that is due to the high resistence its suction system is inducing, because it is empty and it still stays up, I would try to turn the power settings a little lower, or it is experiencing high pressure from operation. Also, if you could adjust the bristles, or losen around the air vents. This should do the trick.
Thankyou, :)
