No power to thermastat

The pressure chamber or hose (pressure chamber to sump) may be blocked and the microswitch is being activated because the water is not entering the tank quick enough. Isolate from electric, remove lid and left panel (looking from the front). There is a plastic chamber bottom right of left side with two microswitches, either this is blocked or the hose that runs from it to the right and along the back of the kick panel and into the sump. Clear either or both (make sure all hoses are pushed true when repositioning).

How do i fit micrio switch

The microswitch is located inside the pressure chamber. The pump will have to be opened, the motor and pressure chamber will have to be removed out the top of the casing as one piece, the pressure chamber has to be opened and the internal components will come off the bottom, you can access the micro switch at that point. You can also download the installation manual from the Saniflo website.

Sani plus motor continuing to stay on after the water has gone.

The Saniplus works on a pressure chamber ((float switch) i suggest that you remove all the piping attached the unit, remove the pump completely out the back of the toilet, pry open the lid using a flat head screwdriver, remove 2 or 3 screws from front and back of pump casing. Then the motor with pressure chamber can be lifted out the top of the casing as 1 piece. The pressure chamber is a white casing attached to the motor and where the power cord comes out the top. At the bottom of the pressure chamber you will find a black rubber membrane, it might be warped or solids could be build up at the bottom not allowing it to shut off. If you need to order parts you will have to call Saniflos hotline.

After I flush the toilet, the motor continues to run and not stop. The only way to stop the motor is to kill the power to the unit. I was told the the float or float switch may be stuck. I was wondering...

Yeah most likely the float switch may be stuck in the on position. Remove the pump out the back of the toilet, pry open the lid using a flat head screwdriver, remove 2 or 3 screws from front and back of pump casing, remove the motor and pressure chamber out the top as one piece, place it on a work bench, the pressure chamber is the white casing where the power cord comes out the top. There is a black rubber membrane at the bottom of the pressure chamber, inspect it and make sure is not warped or that there are no solids build up at the bottom.

Pump will not cut out

Water pressure makes the unit kick on and off. There is a pressure chamber (float switch) inside the pump casing. You will need to pry open the lid with a flat head screwdriver, remove 2 screws in front and 1 at the back of the pump casing. The motor with pressure chamber can be removed from the top, the pressure chamber is a small white casing attached to the motor (power cord comes out the top) at the bottom of the pressure chamber you will find a black rubber membrane (float switch) there could be a piece of hard solid stuck at the bottom not allowing it to shut off or the membrane could be warped, if is warped it will need to be replaced. Also the micro switch inside the pressure chamber may be stuck in the on position. Pressing up and down on the membrane manually will help loosen up the micro switch in case is stuck.

As it takes on water it overfills and leaks out of the drawer. An earlier answer suggests it is the pressure system. What is this and how do i fix it?

The pressure system you refer to, is the water level switch and pressure chamber, the small hose leading to the pressure switch can get blocked and cause the washer to overfill.
To check the hose, remove the lower rear panel of washer, at the bottom right you will see a large black hose, attached to this is the pressure chamber hose leading to the pressure switch.
Remove the small plastic hose and check for blockage here and in the black hose where the small hose is fastened too.
If it still overfills, then could be a faulty water level switch..

How do i hook my manifold gauges to my residental condensing unit to check pressures

The AC manifold gauges set have the three chambers: the low pressure chamber (left side), utility chamber (middle), and the high pressure chamber (right side).

When technicians connect the HVAC manifold gauge to the air conditioner units, he connects the low pressure side of air conditioner unit to low pressure gauge side.

If he wants to read the pressure in discharge line he connects the high pressure gauge hose to the air conditioner high pressure side.

The utility port (the middle chamber) is a place you connect the hose to vacuum pump, recovery units or add or remove refrigerant from AC units.

Air conditioning gauges is used to measure air conditioner units pressure within closed-system to evaluate or troubleshoot the AC units. Gauges manifold set is the most frequently used item when it comes to refrigerant or pressure.

Air conditioning gauge set allows the HVAC technician to check AC units operating pressures, transfer AC refrigerant, pressure test system, purge the system with nitrogen, and perform other necessary tasks.

The gauges manifold set includes the hoses, the manifold, the valves, the compound gauge (low pressure gauges) and high pressure gauge.

Machine doesn't spin properly, drum goes round but only slowly

It could just be the load is out of balance which would mean redistributing the load or adding something if you only have one or two items in the drum. The other scenario is the pressure chamber has blocked and the machine thinks the drum is still full of water. To find out if it is the pressure chamber remove the lid off the machine, locate the pressure switch, it will probably be round in shape and about 3 inches across with a few wires comeing out one side and a rubber hose connected to the under side. Remove this hose carefully and listen for a click as you do so, if the chamber is blocked you will hear the click because the switch is resetting. Now follow the hose down and it will lead you to the chamber, remove it and clean it out, dont be tempted to just blow down the pipe because that is not a lasting solution and will block again in no time. Before putting your hands in the machine turn off the power and remove the mains plug.

It may clear from time to time allowing for the occasional instance when it would spin as normal. The only real way to clear the blockage is to remove the chamber and wash it out under running water, although there are those that say ‘just blow down the air hose’ Believe me this is only a temporary solution because the fault will return. On the other hand it could be the switch is faulty in which case you will need a new one.
The pressure chamber is located under the machine at the rear and will need to be removed from the tub to be cleaned.(you never stated which model you have) so I can only assume it is a split tub type. If in doubt locate the switch by removing the lid of the machine and it is (a round object about 3” across with wires on one side and a small bore air hose underneath).Follow the hose down to the pressure chamber.

Washing machine fills with water but wont shut off

If the water continues to come in without the washer being on, then you have faulty inlet valve, replace.
If it stops when you turn m/c off, then you probably have a sticking water level switch, or a blocked pressure chamber and /or pressure hose.
the pressure chamber and hose are located at the rear right side of the m/c .
Remove lower rear panel, and remove the hose with the long thin hose attached to it this is the pressure chamber and hose, thoroughly clean and fit back.Test it for leaks.
This should solve the problem.
While in the back I would suggest you remove large black hose and clean the filter located in there as this could also be a factor in it overfilling.
Plz rate my solution.
