Pentax water pump 1/2 hp when pump starts works well but pump does not cut out when all taps in the house are closed

The water pump in a Bissell CrossWave is a vital component that is responsible for pumping water from the tank and through the cleaning brushes. If the water pump is not functioning properly, it can cause the CrossWave to perform poorly or not work at all. Here is a breakdown of the parts that make up the water pump in a Bissell CrossWave:

1. Motor: The motor is responsible for driving the pump and is typically a small, electric motor.
2. Impeller: The impeller is a small, rotating blade that is attached to the motor shaft. It helps to move water through the pump by creating a suction effect.
3. Housing: The housing is a container that encloses the motor and impeller. It is typically made of plastic and is sealed to prevent water from leaking out.
4. Inlet and outlet ports: The inlet and outlet ports are openings in the housing through which water enters and exits the pump.
5. Seals: Seals are used to prevent water from leaking out of the pump and are typically made of rubber or a similar material.
6. Gasket: The gasket is a flat, circular piece of material that is used to seal the housing to the body of the CrossWave.

If any of these parts are damaged or not functioning properly, it can cause the water pump to break down and may require repair or replacement. I recommend contacting Bissell or a professional repair service for assistance if you are experiencing issues with the water pump on your CrossWave.

It is not an easy project. It could be several issues.
1) Heater clogged up.
2) Solenoid valve(s) not working.
3) Pump not pumping.

Here is one thing you can try. Fill the bladder with hot tap water. Try spraying form the hose only. (Do not attach any of the attachments to it. Just spray directly from the hose.) It may take a minute or so but many times it can prime itself and start working after doing this.

If it is any of the problems above this will not fix it.

The question makes perfect sense assuming we are talking about the ShopVacPumpVac. These devices are, essentially, a combination shop vac and sump pump. For those answering the question, you can see literature on these vacuum/sumps here: https://www.shopvac.com/includes/streamPDF.asp?loc=pdf&id=Shop-Vac-Pump-It-Out .

When I have experienced the loss of drainage, I have found a couple obvious problems and solutions.

First, make sure that the garden/discharge hose is not kinked at any point along the line from the vacuum to the outside. If kinked, the line will not drain.

Second, the baffle can become blocked or clogged. Take the following steps to determine if your baffle is clogged and to clear the clog:

1. Turn off and unplug the vacuum.
2. Unclip the two lid clips.
3. Lift the lid of the vacuum. When properly set up, the baffle hangs below the filter housing on an opaque hose about 1 foot in length.
4. Grasp that hose and pull firmly downward. Once removed, I take that hose and the attached baffle to an outside garden hose.
5. Pull the baffle off the opaque hose.
6. Spray water from your garden hose through the opaque hose to make sure it is clear.
7. Spray the baffle clear.
8. Lightly tap the port of the baffle, where the opaque hose has been inserted. Most of my clogs have been the result of hair balls (or worse) at this point. Just tap any blockage out and rinse.

Third, reattach the baffle to the opaque hose. Reattach the opaque hose and baffle to the motor under the filter housing. Set the vacuum top on the canister. Click the locking clamps closed.

If this doesn't result in clearing the clog and allowing it to drain, then you are in the exact spot I am right now. If I figure out this new problem, I will update further. But I have cleared this kind of clog maybe five times in the six months I've been using this new Shop Vac Sump Vac

You can disassemble the unit and check to see if the pump motor has seized.

the motor has a black, red and green wire attached, is encased in a plastic housing, and is right next to the vacuum assembly. Don't cut the line attached to the plastic housing, you don't need to and it can be a pain to reattach later. just slide the whole white housing up towards the black vacuum assembly, and undo the wire leads attached to the motor, they just pull off (make sure it's not plugged in) making sure to note which wire attaches to which lead... i marked each lead with a colored marker to be sure.

Use a pair of pliers to turn the drive shaft if it has seized, and be sure not to lose the small rubber o-ring that sits around the shaft. Lubricate at the base where the drive shaft meets the motor with just a drop of 3-in-1 electric motor oil and then reassemble the housing, attach the leads, seat the motor back into the seating (make sure the bottom nozzle goes into the green water feed coupler!) and reassemble the case.

worked like a cham for me and i saved $10

worked well for me, if it still doesn't work you could buy a new pump and install it. they go for around $10 on ebay and amazon.com

I was mopping with mine a couple months ago when it stopped producing steam. I pumped it several times resulting in a really loud pop (sounded like a .22 going off) followed by a large release of steam from the housing followed by water trailing on the floor. I immediately attributed it to an overpressurization and either a housing or hose failing.

Well several months later and enough nagging from my wife, I finally delved into it. I removed the housing screws from the back side (about 8 small recessed screws). After some wrestling with the housing to free it, I was able to examine the inside. I quickly found the issue. The hose that comes off of the top of the steam chamber and goes to the mop head had indeed failed (presumably from a blockage of sediment / calcium). The hose ruptured right at the top where it connects to the steam chamber where I found about a 1/4" hole.

I was able to remove the hose. I found a long spring inside the hose. (I'm guessing it is to try to prevent blockages.) I blew threw the hose and a good size cloud of a white powdery substance came out. I ran the spring back and forth inside the hose to ensure there were no other obstructions. Fortunately the failure occured close enough to the end of the hose that I was able to trim off the rupture and resecure it with the spring clamp.

I put everything back together and now it works perfectly again. Distilled water from now on (we're on a community well system) and an occasional flush with vinegar should prevent it from happening again.

This is a common problem known by repairers. What happens is residue gets stuck in the seals. The next time you use the machine and press the trigger the seals stay open and water leaks continually. It was suggested that maybe after you finish using the machine you do a whole tank of plain water to rinse it out but I haven't had any luck with that. I am stuck with a machine that doesn't work.

Ensure you have water in tank and solution (or water in solution tank). When you start the vacuum up, the pump starts to prime itself. If you have air in the system, it takes a little longer to prime. Allow the vacuum to run for 1 minute before attempting to pull the trigger. Then pull the trigger.

If this doesn't work, you'll need to open the unit up and check the hoses for any clogs, and next test the pump to see if it is functioning.

Common on Armonia...
There is no water in the system, so the pump is pumping air!!
you have to push on the usual button but make sure the hot water button (for tea for ex) on the right side (same as steam opening valve) of the machine is open. This will allow the water to re-flow through the system. Once water is coming out again, close hose, and stop water button. Once hose is closed, and you repush the water button, it will flow again through the coffee hole.
Voila
