Polaris Pool Vacuum Not Moving? Here’s Why & How to Fix

Polaris Pool Vacuum Not Moving? Troubleshooting Guide

If your Polaris pool vacuum is stubbornly refusing to move, it can be frustrating. Before calling a repair technician, there are several common issues you can check yourself. This guide will walk you through potential causes and how to fix them, helping you get your pool vacuum back to work.

1. Checking the Power Supply & Connections

A good place to start is to ensure that your Polaris is getting power and that all connections are secure.

1.1. Power Outlet Verification

• Confirm Power: Plug a different appliance into the outlet that powers the Polaris. If the other appliance doesn’t work, you know the problem lies with the outlet itself. You may need to reset a breaker or call an electrician.
• GFCI Outlet Check: If it’s a GFCI (Ground Fault Circuit Interrupter) outlet, try pressing the "Reset" button. These outlets can trip, cutting off power.

1.2. Cord Inspection

• Visual Inspection: Carefully examine the entire length of the Polaris power cord for any cuts, fraying, or exposed wires. Do not use the vacuum if you find any damage – replace the cord or consult a professional.
• Connection Security: Ensure the cord is firmly plugged into both the power outlet and the Polaris unit itself.

1.3. Transformer Unit Examination

• Power Indicator Light: Look for a power indicator light on the transformer. If the light is off, even with a working outlet, the transformer itself might be faulty and may need replacement.
• Overheat Protection: Some transformers have built-in overheat protection. Let it cool down completely and try again.

2. Analyzing Water Flow and Pressure

Polaris vacuums rely on water pressure to move. Insufficient pressure is a frequent cause of movement problems.

2.1. Filter Cleanliness

A clogged pool filter restricts water flow, reducing the pressure available to the Polaris.

• Backwashing or Cleaning: Backwash your sand or DE filter according to the manufacturer’s instructions. For cartridge filters, remove the cartridge and thoroughly rinse it with a garden hose.
• Frequency: Clean your filter regularly, especially during periods of heavy pool use or after storms.

2.2. Skimmer Basket Condition

A full skimmer basket also reduces water flow.

• Emptying Regularly: Empty the skimmer basket at least once a week, and more often if necessary.
• Debris Removal: Remove any large debris, leaves, or other obstructions from the skimmer basket.

2.3. Dedicated Polaris Booster Pump Inspection (if applicable)

If your Polaris model uses a dedicated booster pump:

• Pump Operation: Ensure the booster pump is running correctly. Listen for the motor’s hum. If there’s no sound, check its power supply and connections, similar to the Polaris’ main power supply.
• Pump Strainer Basket: Clean the strainer basket located before the booster pump to remove any debris that may be blocking the water flow.
• Pump Impeller: A blocked impeller will prevent the pump from generating sufficient pressure. Consult your pump’s manual on how to access and clean the impeller.

3. Investigating Polaris Components

Now, let’s examine the vacuum cleaner itself.

3.1. Wheel Rotation and Obstructions

• Manual Check: Lift the Polaris out of the water and manually turn each wheel. They should rotate freely.
• Debris Removal: Inspect the wheels for any trapped debris, such as pebbles, leaves, or hair. Remove any obstructions.

3.2. Drive Train Inspection

This section deals with components that translate water pressure into movement.

• Belt Examination: Many Polaris models use belts to drive the wheels. Check for signs of wear, cracks, or breakage. A broken or worn belt will need replacement.
• Gear Assembly: If your model has gears, inspect them for damage or stripped teeth. Damaged gears prevent proper power transmission.

3.3. Sweep Hose Assessment

• Hose Blockages: Disconnect the sweep hose and check for any blockages. Use a garden hose to flush out any debris.
• Hose Condition: Look for cracks or leaks in the sweep hose. Air leaks reduce suction and can impede movement. Replace the hose if necessary.
• Sweep Hose Nozzle: Ensure the sweep hose nozzle is properly aimed and not obstructed.
  

  3.4 Tail Sweep Operation

Many Polaris cleaners have a tail sweep with a scrubbing brush.

• Inspection: Make sure the tail sweep moves freely, and that its scrubbing brush is intact.
• Replacement: Replace the tail sweep if the bristles are worn or broken, or if the tail sweep itself has become brittle.

4. Diagnosing Polaris Float and Hose Length

Proper float adjustment and hose length are crucial for optimal performance.

4.1. Float Adjustment

• Float Position: The float helps the Polaris navigate and prevents it from getting stuck. Adjust the float according to the manufacturer’s instructions. A float that’s too high or too low can hinder movement.
• Adjusting Tools: Usually, float adjustment involves moving the float up or down the feed hose.

4.2. Hose Length Verification

• Adequate Length: The hose should be long enough to allow the Polaris to reach all areas of the pool. Too short a hose will restrict its movement.
• Excessive Length: Conversely, a hose that’s too long can tangle and impede movement. Trim the hose if necessary, following the manufacturer’s recommendations.

5. Pressure Relief Valve & In-Line Filter

These components help regulate flow and keep debris out of the vacuum.

5.1. Pressure Relief Valve (PRV) Inspection

• Function: The PRV prevents excessive pressure from damaging the Polaris.
• Malfunction: A faulty PRV can release too much pressure, reducing the power available for movement. Inspect the PRV for damage or clogs. It may need replacement.

5.2. In-Line Filter Screen Cleaning

• Location: This filter is usually located within the hose near the wall connection.
• Cleaning: Remove and clean the filter screen to remove any debris that may be restricting water flow.

6. Table Summary of Issues and Resolutions

Problem	Possible Cause	Solution
No Movement at All	No Power	Check outlet, cord, and transformer.
Sluggish or Erratic Movement	Low Water Pressure	Clean filter, empty skimmer, inspect booster pump (if applicable).
Wheels Not Turning	Blocked Wheels	Remove debris from wheels.
Limited Range of Motion	Incorrect Float Adjustment or Hose Length	Adjust float and hose length as per the manufacturer’s instructions.
Reduced Suction	Blocked or Leaking Sweep Hose	Check for blockages and leaks in the sweep hose.
Inadequate Pressure at Cleaner	Faulty PRV	Inspect and replace PRV if necessary.
General Restricted Water Flow to Cleaner	In-Line Filter Screen	Inspect and clean in-line filter screen

So, next time your polaris pool vacuum not moving, remember these tips! Hope this helps get your pool cleaner back in action. Happy swimming!
