Question about Vacuums
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.

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.

Thank you Alex! I have a model V3825 and the 3 wires going to the JST connector are red, white and black, not brown.

Well my food saver is brand new so I'll just return it and try my luck with another one. Something this expensive should work without tape or disconnecting wires.

Fixed my Food Saver V3440 doing exactly what Alex said to do! Disconnected the wires that run from the drip tray sensor and it worked like a charm!

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 used a blow dryer and the light went off in about 3 seconds. Why would you ever disconnect wires??

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!

Just used the hair dryer that was suggested. Work like a charm!

Did what steve 122885 suggested.. Used compressed air in every hole I could find. Works again. V3420. Thanks

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!

As db255 said, but used black electrical tape to cover all 3 contacts under lower tray. Worked immediately and just fine. Thanks db255.

Hair dryer worked perfectly. Just blew the removable tray then the inside of where it sits and the upper tray and bam, it worked just fine. Thanks, saved me a big headache, as I was making sous vide chicken.

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.
