Question about Plumbing

1 Answer

My water pump stops and starts. the contacts on the pressure switch are closed and voltage is going to the pump. The pump will run for a few minutes but not long enough to reach the 60 # to turn off the pressure switch, but the pump will stop after several minutes it will start again an pump for another several minutes and then quit again. It is a brand new pump. Is there a thermal overload in the motor?

A lot of these pumps do have automatic thermal switches built into the motor end cap, Double check that its being fed the name plate voltage and that the voltage doesn't drop when the pump is running (which would indicate a loose or bad connection or just undersized wire in the circuit)

My gould well water pump would not stop so is bought a new pressure switch which i installed and same thing. can you help me please


Sounds like the foot valve may be loosing it's prime. I would let it pump for a few minutes and then shut it off. Then after a few minutes disconnect the line going into the well. If the line has water in it and the water level is going down, you have either a bad foot valve or a leak in the lines going down into the well. It could be as simple as a loose connection. Hope this helps. I use to sale well pumps and have seen this many times. If you let the problem continue and the pump continues running it will throw the overload or will burn the pump motor up.

Well Pressure Switch Adjustment Water Well Problems


1fa4b10.jpgIf you have a water well to supply your water needs, then you also have a well pump is some form and a well pressure switch that controls the water well pump and the pressures that it turns on and off at. Making the adjustments to this switch can be confusing, I will try to take away some of the confusion for you. There are many types of well pressure switches made. I will describe the adjustment of the most common type of switch and you can possibly translate from there if you have a different type of well pump pressure switch.

  1. Turn off the power to the well pump before making any adjustments. The blue flash from the arc when you short out the power is scary and leaves you seeing stars for a time.
  2. Drain all of the water pressure from the system and check that you have air pressure in your well pump pressure tank. If you intend to set the cut in of the pump at 30 PSI then make sure there is 28 PSI in the air part of the tank. Always 2 PSI less than your cut in pressure.
  3. Start the pump, run water, and then observe the pressures as the pump starts and stops. Remove power when adjusting to avoid the blue flash…you are working in close proximity to the electrical contacts of the switch.
  4. To raise the cut in pressure turn the taller center nut down to increase the spring pressure. This will start the pump at a higher pressure. To lower the start pressure turn the nut up or counter clockwise.
  5. To change the differential pressure, the difference between the start and stop pressures, you need to adjust the smaller nut that is on the side of the pressure switch. Turning this nut down will increase the differential pressure and likewise turning this nut counter clockwise or up will lower the differential pressure.

This process can take some time, but it will be worth it to have your pump and water system operating efficiently. You also can set the well water pressures to your liking.
This is a basic guide to help you fine tune your water well pump and your well pump pressure tank, along with your water pump pressure switch, so that they all work together to give you a good stable supply of well water.

What is this problem - Karcher 3.86 electric pressure washer: humming noise, plug gets very hot, then unit shuts down?


Your pressure washer is either not fitted with a run/stop device in which case like mine you have to switch off within a few seconds of closing the trigger. Check your model features?
The humming noise is the motor stalled out against the pump because there is nowhere for the water to go. The shutoff is caused by the safety overload switching off after overheat.
Or, it has a pressure operated run/stop which is not working. Because water and electricity don't mix, I would suggest getting more specific help. You can download Karcher manuals /spares lists online from Karcher specialists but remember electricity is the silent killer.

My ice machine manitowoc q 132a starts up stops after few seconds while water pump start


There is a high pressure switch that stops the unit running if a fan fails or the condenser is clogged. Next time you start the ice machine, watch the bottom led on the pcb. It will tell you if there is a fault. Meantime, reset the hp switch and clean the condenser thoroughly.

1998 chevy astro van sometimes works, sometimes not.? At timesm rarely, the astro will crank but will not start. Fuel pump not cycling and making its hum noise so I changed the fuel pump with an AC Delco...


When you first turn on the key, no crank, the fuel pump should run for a few seconds then stop. There shows to be an oil pressure switch in parallel with the fuel pump relay. It's just a redundant power supply to the fuel pump. Once it cranks enough to bring up oil pressure and the switch closes, the pump will run even w/o the relay. Both the fuel pump relay and oil pressure switch get voltage from the ecm b fuse.
At the fuel pump connector, check voltage and ground, when problem is ongoing. Gray wire is voltage--black wire is ground.
You could pull the fuel pump relay, use jumper wire between terminals on load side of relay. The load side is that line with arrow head, when energized that line moves to the other terminal. As you can see, the orange wire is hot all the time, the gray wire carries voltage to fuel pump. If it runs with jumper, then check control side of relay, the control side has to have voltage and ground, dark green wire with white tracer is voltage comes from pcm. The black wire is ground.

Bosch dishwasher Water pump not stopping


Hi.

You need to replace the pressure switch located near to the pump, in the drain assembly.
The main function of the pressure switch is to turn off pump when there is no more water.
The pressure switch can be tested reading ohms on switch contacts and jumping the switch. This must be done by a technician.

You can get parts and a quote on repair calling Bosch at the number listed on the manual.

Regards.

My sku 509560 has begun to stop and then restart after 15 minutes or so? It them runs for 10 minutes and stops again. Is it fixable?


Yes, it can be fixed.Assuming that your water system is pressurized, take the following steps;
1. Shut the power off the lines going to the pump
motor.
2. Drain all the water inside the pressure tank by
opening the drain plug. After emptying the tank,
replace the drain plug.
3. Unscrew the priming port plug and fill it full with
water. And at the same time fully close the
flow control valve.
4. Put the power back on, and slowly open the
flow control valve until the water flow stabilize at
20 or 30 psi at the pressure gage. This could be
at 1/4 open or 1/3 open, depending on the water
supply at the suction point.
5. Check and set the pressure switch to be off
at 40 psi.
This will solve your problem.

Pump spinning but not getting up to speed then shuts off


You have a pressurized system using a pressure tank.This is a case of an air logged pressure tank. Meaning there is more air than water in the pressure tank. The pressure tank must hold 2/3 water and 1/3 air of its total volume. Installed at the tank is the air volume control to take care of this proportion. Should the air volume control malfunction or becomes defective, the air-water ratio is affected. And then,
the pressure tank becomes either air logged or water
logged.
SOLUTION:
1. Shut the power off, and open the discharge line
gate valve to flush the water in the pipe lines.
2. Open the drain plug of the pressure tank to empty
all the water at the pressure tank.
3. Close the drain plug, and put the power on.
4. Start the pump, and set the flow control valve 1/4
open.
5. The pump will normally run.

Letters H & F start flashing mid cycle which stops the cycle


error code  -----  F/H ----------- reason ----------- No water detected entering machine or Pressure switch trip not detected.
If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed.
Or
If the control has turned the water valves on and after 8 minutes the flow meter has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off and the error code will flash.


solution to resolve  -----------   Press PAUSE/CANCEL twice to clear the display.
  • If there is no water in the unit:
    1. Make sure that both valves at the water source(s) are turned on all the way.
    2. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves 
    3. Verify inlet valve operation
  • If there is water in the unit:
    1. Verify Drain pump operation
    2. Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch
  • Verify there is not a siphon problem
  • Verify wire harness connections to:Inlet Valves, Pressure Switch, Drain Pump, Flow Meter, and Central Control Unit (CCU)
  • Check all hoses for possible leaks
  • Verify pressure switch operation
  • Verify flow meter operation
  • Verify CCU operati
