I have a 4310. The three point lifts only under high rpm and won't lift any weight at all. Cleaned screen and replaced suction and trans filters. Still have problem.

The lint filter on the water tank cover may be the reason for that. Try cleaning the Filters. Clean the Flow Indicator Filter: Unscrew the Flow Indicator Cap to remove it. Lift out the rotor and the filter is under it. Lift out the filter and clean. The Water Tank Filter looks like a screen on the underneath the front area of the cover. It's held in with tension and just pulls out. Clean it and replace it. Hope that Helped but if it didn't call the consumer care at 1-800-237-7691

could be fuel elated, there are two fuel pumps, the high pressure pump to feed the injector system and the lift pump to get fuel from tank to the high pressure pump. Check fuel filter also and start there. The fuel pumps are expensive. What have you checked so far and eliminated?

Filter in tank remove dash its under the plate ..if you unbolt the tank at back you can lift rear whitch may give you enough room to get to the wires .. Watch do not lift to high,, tank,,puts a strain on outlet can break ';';';

It looks like my cleaner. While it is hooked up to the filter, lift the unit, keep the suction side under water and flip it over. The feet should be moving. Feel for suction on the inlet on the underside.
There is a waterwheel inside the suction. Is it rotating? Is the suction hole clear, sometimes stones, acorns or other solid items get stuck in the suction that stop the water motor.
If there is something stuck inside or if the wheel is not moving, on my unit there are a few screws that can be removed to inspect inside. Naturally before doing this, disconnect the cleaner, drain it and take it to a location where it can be partially disassembled to inspect.

the engine ofr the 95 Le Sabre is most easily taken out by dropping the sub frame. Here's how its done:

1. Lift the car on jack stands as high as you can get it **DO NOT FORGET TO CHUCK THE REAR WHEELS***
2. Begin by removing the battery cable, air filter hose and air filter box, the front wheels and disconnecting all the sensors from the wiring harness there are 2 main harness connectors that should take care of all the sensors depending on year and model. Also remove power steering pump and Cruise control.( this includes the starter cables and remove the A/C compressor* from the engine its self.
3. The next step is to remove the exhaust manifold that is bolted to the engine (trust me it saves about an hour of frustration, and saves you an exhaust gasket)
4. next get a hoist or engine crane strapped to the motor and support the engines weight. Then begin taking the engine cradle out by removing the 4 bolts out of the sub frame.
5. next lower the motor and trans mission from the vehicle. and pull it from under the car.
6. remove the transmission bolts (there are 5) that are at various circumference of the motor to trans
7. Now support the transmission and lift the engine off the engine cradle (sub frame) and replace the new engine into the old engines place.
8. bolt the engine to the transmission and replace the starter.
9. slide the engine back under the vehicle and replace the lift or hoist back on the engine.
10. lift the engine back into place and adjust the sub frame into place and bolt that back together.
11. replace the exhaust manifold.
12. replace the engine wiring harness, A/C compressor, Power steering pump, cruise control, and attach the starter wires.
13. reconnect the air filter hose and air filter box.
14. check motors oil level, and oil filter.
15.reconnect battery

I had the same problem. In the water resevoir, there is a red flap that allows the dirty water to flow back into the water tank. Lift that flap up and there is a small red screen. Pop that screen out with a butter knife and rinse it out. I have dogs in my house and that screen was blocked by dog hair. I cleaned the screen, popped it back in and it works like a new machine. You would think Bissell would address this roblem on their web site but they don't.

Check to make sure that you somehow did not disconnect or move any linkage that goes from the carburetor (or injection air inlet if you have f/i) to the transmission. on many vehicles this linkage controls internal trans pressure and can influence shift points and application harshness. Your post indicates that you were sleeping when you changed the filter...Don't work on cars unless you are awake!!!
PS: If you have f/i, you would have to be underneath the car...did you somehow cut a wire or catch trans linkage when lifting it?

Sounds like a bad motor. Could be either foot motor or main motor either way cost will be more than half of the unit.

that is normal for the vacume to shut off if the motor overheats you must keep teh dirt cup clean and empty and all the filters clean, when you empty the dirt cup if you have a lot of pet hair take the hose off and make sure that it is clean as well, and do not try to pick up any of those cleaning wipes that will stop it up real quick
