Integrated fridge door keeps springing open. what is causing this?

no maker ,no model number told
and moved this from cars to fridge.

U seem to have a good handle on things but the flapper door is still not operating properly. Rather than create more agita for yourself, you just might want to consider replacing the assembly if not that expensive. OR experiment with various flapper door openings till you get a more reasonable refrig temp since 25 is too low. Aim for 35 - 38 degrees.

It's telling you it has a fault, you have to find out who is doing the warranty work for Baumatic now, by law they have to honor the warranty.

The door tension is set with a spring. You need to pull the unit out part way and look on the left and right side bottom area near the front. The spring can be adjusted by selecting a different hole in the bracket that it is attached to.

Open the bag door, remove the bag (leave door open)and then with a hammer and a blunt instrument(wooden dowel) Strike the side rubber "bumper" rails towards the open door side of the machine from the back of the vacuum. You should get it started and then it should easily pull out from both sides. you can remove the bottom of the vacuum and remove the cord "guard" to allow the cord to go thru also. The back is held on by the union of these two halves by dowel pins(plastic nubs) Sometimes the "spring" mechanism gets jammed from over pulling. Just simply roll the smaller wheel to retract the cord manually. You could try spraying the rollers with a silicone or graphite type spray to allow free movement of the spring. Hopes this helps.

If your dishwasher door is not closing properly or has developed a leak, it may be time to replace the entire door assembly. Some other signs of a defective door include sagging, difficulty pulling the door back up into a closed position and a door that feels heavier as it drops open. Replacing a dishwasher door is not that hard, but includes several springs and hinges that must be aligned correctly or the door will not fit correctly in the opening.

1. tep 1 Unplug the dishwasher and shut off the water before attempting to remove any parts. If you cannot reach the electrical outlet, you can turn off the breaker switch that controls the electricity for the kitchen. Remove the drain hose that runs from the dishwasher unit to the sink drain.
   
2. Step 2 Pull the dishwasher out from the cabinet until you have clear access to the side of the unit. Ask a friend for help with this part if the unit is too heavy for you to slide out without straining your back.
   
3. Step 3 Check your dishwasher's owner's manual to find out exactly how the outer door panels are removed. Some models have a two-panel door where the control panel must be removed before the lower panel will come off. Otherwise, the door panel should be one solid piece or a two-piece assembly that allows the lower section to be removed separately to access the springs and hinges.
   
4. Step 4 Remove the springs at the bottom of the door. Depending on the type of dishwasher you have, there may be a tension adjustment dial or simply a series of holes at different distances from the edge of the unit. If you have a tension controller, adjust it to a loose setting to make it easier to remove the door springs. Unhook the door springs from the hinge plate. Some dishwashers may have a cable and pulley system attached to the door springs. Check your owner's manual for removal instructions if this is the case with your model.
   
5. Step 5 Use pliers to gently pull back on the door hinge plate's tab until the slot opens for the hinge pin to come out. Take out the screws holding the door hinge plate onto the front of the door panel. Hold onto the door assembly while gradually opening the door. Once the door drops down, you should be able to remove it by sliding the door off the hinge pinAlways wear safety glasses when working with the springs and hinges involved with a dishwasher door assembly. These items can fly off at high speed and cause serious injury to the eye.
   

Seals rarely fail most likely needs hinges replaced,parts quite cheap

The top hinge of my Neff integrated fridge freezer has broken so the door won't open and shut properly. As a temporary repair I intend to swop the hinges around -replacing the top hinge with the middle one but can't see how to remove the hinges. Can anyone help?

Right on the top edge of the machine - get a torch and look directly under the worktop - there are two hex-head screwws about 4" in from each side. Clockwise to increase spring tension.
