Why does my hot tub pump only work on low speed?

A: When your 2-speed hot tub pump only works on low speed, and never kicks into high speed, there are four possible solutions to check. First , if you are pushing an air switch button, check that the air hose is not crimped or disconnected.

What should I do if my hot tub wont turn on?

Set the thermostat completely counterclockwise. Put hot tub in time clock mode. Check to see the motor still changes over by choosing high speed. If it doesn’t, turn timer and then thermostat one at a time completely clockwise. If high speed turns on with either then swap wires on the motor because the low and high-speed contacts are backward.

How can I tell if my hot tub motor is damaged?

Make sure that the power supply is active and that all switches are ‘on’. Use a mains tester to check that there is power arriving at the pump. If the pump makes a brief humming noise this will warn you that the pump has an obstruction or the motor is damaged. You will have to check the pump and motor.

When do you need to replace a hot tub motor?

Make sure the water level is high enough to cover the pump. The bearings on the central shaft of the motor do wear. When these bearings start to break down, they become noisy. You will need to examine the bearings and replace any that are worn or replace the motor.

What kind of motor does a 1 Speed Hot Tub use?

A single 3450 RPM rating shows that your pump is using a 1 speed motor. A single 1725 rpm rating means you have circ pump motor, ratings of 2850 rpm or 1425 rpm mean you have a 50 hertz overseas motor. Hot Tub Outpost offers most major brand 1 and 2-speed pumps including Aqua-Flo, Waterway and discount custom pumps too.

How can I tell if my hot tub pump is dual speed?

Another way of checking if the pump is single speed or dual speed is if the label shows either 1 or 2 rpm ratings. For example a 3450/1725 RPM rating shows that it is a 2 speed motor/pump. A single 3450 RPM rating shows that your pump is using a 1 speed motor.

What kind of pump does a hot tub have?

Spas and hot tubs with one pump usually have a 2-speed motor, operating on low speed most of the time, and on high speed when using the tub with the jets. Here’s a simple way to troubleshoot your spa or hot tub pump. Hot Tub Blogs should do this more often – These are our most Frequently Asked Questions about spa pump repair.

Do you need two speeds for a pool pump?

Welcome to TFP! 1) You want two speeds, as low speed will save you almost 50% on your electrical usage due to the pump. However, you do not NEED two speeds. You can easily wire it to your existing wiring connecting only high or only low speed to one hot wire and common to the other hot wire.

How do you know if your hot tub pump is bad?

How do you know if your hot tub pump is bad? When it comes to hot tub pumps there are several signs that clearly indicate failure, and they include a humming noise, a whining noise, or leaks under the pump. Typically humming noises are caused by the motor not turning, a frozen shaft, frozen or stalled bearings, or a frozen impeller.

Is there a low speed or high speed pool pump?

Still, a few two-speed designs only have a low-speed main winding. This design always starts at high speed and switches to the low speed run winding within a couple of seconds. This motor was a less expensive design since there was no low-speed start windings or a start capacitor.

Why does my hot tub make a low noise?

A: If your spa pump never actually turns on, it only makes a low noise, until the circuit breaker trips, check these things. First, would be the capacitor on the motor. This cylindrical “battery” provides extra starting power, and these can go bad after many years.

Are there any problems with my hot tub?

Hot tub problems come in all shapes and sizes. What follows are some of the most common pump problems that arise when hot tub troubleshooting. Check to see if the high speed still works. Then check the power for correct voltage.

Is it OK to leave my hot tub running without a filter?

But running the pump for long periods of time without the filter could lead to clogged pump impellers, and rapid water quality problems. However, if your spa filter is cracked or broken, or if your dog carried off and buried your filter – it’s better to leave the pump running on low speed, than to shut down the spa completely.

What to do if your hot tub has a short?

If high and low speeds are operating simultaneously, then remove the pump cord and then examine the pump air switch for power. If both have power then there must be wiring trouble inside which has caused a short.

Is the AC motor on my hot tub running?

After replacing the start capacitor, the motor started and is running. It turns out that Spa/hot rub AC motors like this have both a start and run capacitor, as do blowers on forced air furnaces and air conditioning units.

What makes a hot tub start and run?

It helps the motor start. The motor also has a capacitor on the outside, and it’s the run capacitor. That’s the one that was replaced first. After replacing the start capacitor, the motor started and is running.

Why does the spa pump need to be on high?

They provide the circulation for the spa filter and heater and give an extra boost when turning the spa jets on high. And when the spa pump ain’t happy, ain’t nobody happy – that’s because without water flow, there is no filtration, no sanitation and no heating.

Can a two speed pool pump be replaced?

Unfortunately, if the winding is bad, it cannot be replaced and you will need to replace your whole motor. Certain types of two-speed motors actually have two separate windings in one housing. Most have a separate main and phase windings. Still, a few two-speed designs only have a low-speed main winding.

Why is my two speed pool pump not working?

We used it until May when we moved it to a different house. When we set it up again it appeared to be working fine until we tried to switch our two-speed pump from low to high. It made the normal “clunk” sound but there was no increase in the noise which I assume means no increase in RPM.
