6 Signs of a Damaged Water Pump Capacitor to Look For

A water pump capacitor is a tool that helps the water pump turn when it is first turned on. It also helps the electric water pump dynamo turn more smoothly and gain more power. But because it is used so often, the water pump capacitor wears out over time.

Because the water pump capacitor is broken, it can’t work as well as it should and can’t turn as it should. Here are some signs that a water pump capacitor is broken:

1. Weak Pump Thrust

Weak pump thrust is the first sign that a water pump capacitor is broken. This happens when the water pump capacitor isn’t working as well. So the dynamo doesn’t get as much power as it did when the capacitor was working well.

So, the dynamo doesn’t turn as well as it could, which affects the thrust. Even the way he moves is often weak. The water pump’s thrust is how much water it can move from the pump point to the water reservoir.

2. Pump Can’t Turn

The second sign that the water pump capacitor isn’t working is that the water pump won’t turn. This happens because the water pump dynamo isn’t turning steadily enough for the capacitor to work correctly.

Also, the water pump capacitor helps the dynamo turn by keeping the current it needs to keep riding.

So the dynamo depends a lot on how steady the electric current coming from the coil is. So, as long as the current need stays the same and doesn’t go down, the rotation speed can be kept the same.

Because the water pump capacitor is broken, the dynamo is not getting the amount of electricity it needs.

3. Not Able To Hold Electricity

If a water pump capacitor can’t store electricity, that’s another sign that it’s broken. Use a multitester, an avometer and a voltage to determine if the water pump capacitor can keep electric current.

Here are the steps to take to measure a water pump capacitor with an analog multimeter:

  • Provide an analog multitester measuring instrument.
  • Set the selector’s position to the Ohm-meter position.
  • Make sure that the multimeter is in good shape and works well.
  • Then get ready to measure the capacitor and make sure it’s not connected to any cables.
  • Attach the measuring needle to each of the capacitor’s terminals.
  • Look at the pointer on the multitester to see how the measurements turned out.

When measuring a broken capacitor, the pointer moves left and right but doesn’t go back to where it started, and even when the needle position is changed, the needle still doesn’t move.

With a digital multimeter, you can do the following to measure a water pump capacitor:

  • Set the scale selector to the mark or symbol that looks like a capacitor.
  • Join the probe to the end of the capacitor.
  • Check out how the value of the capacitor’s capacitance changed.

When the capacitor is tested with a digital multitester, if the number on the LCD screen is more than 1,300 or goes back to 1, the capacitor can work correctly.

But if the LCD doesn’t show a number, it could be because the capacitor is broken.

4. Interrupted Early Round

The first loop being broken is another sign that the water pump capacitor is broken. This happens because the water pump capacitor’s job is to help the water pump start turning when it is first turned on.

So, if the capacitor gets damaged, the performance will go down.

Capacitors can be hurt so badly that they can’t do their jobs as starting capacitors anymore. If something goes wrong with the water pump’s first rotation, the engine speed of the water pump will slow down.

5. Capacitor Body Grows or Melts

The body of the capacitor swelling or melting is another sign that it is broken and needs to be replaced. If the shape of the capacitor has changed since it was first made, it could mean that it is broken.

The only way to be sure that the capacitor is broken is to look at how it looks. A broken capacitor looks like a swollen or blown-up battery, and electrolyte fluid leaks.

If a capacitor looks like this, it is broken and needs to be replaced.

6. Water Pump Sounds Buzzing And Not Spinning

The water pump buzzing and not turning is another sign that the water pump capacitor is broken.

This happens because the buzzing sound comes from a broken capacitor or a capacitor that is not working as well.

The capacitor also starts the coil running or gives it momentum when it turns.

There’s a buzzing sound, and the water pump can’t turn like it used to.
