Bubbles from water return inlets

This should be an easy problem to fix with this type of automatic pool cleaner. Add return diverters or divert return inlets downward. This will use flow to move cleaner to opposite end. Move hose weight away from cleaner head slightly. You might also have to add additional hose weights.

There are several things that you will want to try if you are not getting adequate suction on these pool cleaners. First and foremost, make sure that you are getting proper water flow to the cleaner. If you are not, the cleaner will not move until the water flow is increased. Clean your baskets and your filter and make sure that they are clear of debris and blockages. Also, make sure that you do not have any leaks in your hoses and connections. Any leakage of air will cause the cleaner not to move correctly.

Cleaner won't leave or rim of edge of pool. Use Pool Pulse to lower flow. Utilize return flow to move cleaner. Adjust hose weight.

POOL PULSE (metering flow)
The Pool Pulse is a flow meter that measures the volume of water flowing through your Zodiac cleaner. It must be used to properly set the flow and can be used as a diagnostic tool when the cleaner isn't running properly. This piece should have been provided with your original box, but if you have lost or discarded the pool pulse flow meter, then you will need to purchase another one either online, or at your local swimming pool retailer. For the following steps (using 2 people is recommended; one poolside and the other at the plumbing manifold.) Vacuum and skimmer valves are located at your plumbing manifold. • Remove the cleaner head. • Attach the Pool Pulse to the end of the hose and keep it under water. • Turn on the filtration system. • For pools with one skimmer, flow is automatically regulated by the Flowkeeper Valve. Insure the blue indicator of the Pool Pulse is in the ideal range (when viewed from the side). • For pools with two or more skimmers, leave the selected skimmer open and slowly close the other skimmer(s) until the blue indicator of the Pool Pulse moves into the ideal range (when viewed from the side). • For pools with a wall vacuum fitting, leave the wall vacuum fitting fully open and slowly close the skimmer valve until the blue indicator of the Pool Pulse moves into the ideal range (when viewed from the side). • Keeping the hose under water, remove the Pool Pulse. Submerge the cleaner head, and when the bubbles stop coming from the extension pipe, attach the hose end. Your installation is now complete.

REGULATING RETURNS Divert the pool return inlets downward - Your Zodiac Automatic Pool Cleaner must move randomly throughout the pool and water circulating at the surface will influence the hose and limit coverage. • To adjust the return inlet: loosen the lock ring and redirect the eyeball downward, then retighten the lock ring. If the eyeball is difficult to adjust, insert a screwdriver inside the eyeball and gently adjust downward. • If the return inlets cannot be pointed downward, then you MUST install Zodiac return line diverters. They are available online or through you local retailer.
This is what a diverter looks like.
Adjusting weight on cleaner: FOLLOW THE GUIDELINES BELOW FOR YOUR SPECIFIC CLEANER MODEL. (Model number is stated on the cover of the manual that came with your cleaner) MODEL# W83251 - Hose weight is not required for this model cleaner in most pools. As a troubleshooting technique to improve coverage or prevent the cleaner from climbing the walls excessively, snap (1) hose weight onto the first hose section, one meter from the cleaner head. MODEL# W03000 - Snap (1) hose weight onto the middle of the first hose section, 1/2 meter from the cleaner head. MODEL# W83215 & W83216 - Snap (2) hose weights onto the middle of the second hose section, 1 1/2 meters from the cleaner head.

If you are still experiencing issues with your cleaner, you have a full 1 year warranty on the cleaner and Zodiac is happy to help you with the ownership! They can be contacted at: 1-888-786-779

Sure hope this takes care of that issue for you, and I look forward to your feedback! Thanks for allowing us to help you out!

You probably just need to redirect the returns in the pool. If they are angled right (or wrong) they will get a current moving in the pool and cause the cleaner to go to one spot and keep it in just that area of the pool.

It sounds like your pool cleaners connection to is lose or cracked at some point. If bubbles are entering at the return line, check the connection and make sure it is tight. Look for cracks in the hose also. Finally, check the gasket in the pump basket for damage or wear. When you find the source of the leak, you can fix it and the cleaner should continue running normally.

Before you go anywhere I would check each piece of hose for leaks. If they are all OK then you need to plug off one end of the suction line and pressure it up at the other end. If the pressure drops then you have a leak in the line. I would check the fitting at the front of the pump first. Short of a cracked pipe that is where most suction leaks occur. This being a vinyl liner pool it could also be just behind the wall also.
If the hoses are Ok and it's not at the front of the pump you may want to get a leak detection service in to help find it. Good luck.

If you are seeing air bubbles in the leaf pot on the pump, you have an air leak on the suction side somewhere between the pump and the pool. Check the pump lid o-ring for any dirt, leaves, etc. Make sure the O-ring on the lid is not cracked, dry (lubrication like Aladdin's Magic Lube) or compressed or flattened. Also check your union or threaded connections to the pump suction (end) to insure they are tight and sealed. If this is an in-ground pool, and equipped with valves to control skimmers and bottom suction, close each valve separately to see if the air bubbles diminish. If the bubbles diminish when the valve is closed, then the air leak is in the closed section from that valve back to the pump. If the air leak increases, the air leak is in the still open line. Since the Kreepy crawly works on suction and increases the vacuum, the air leak will become more apparent, resulting in a loss of pump efficiency and flow, resulting in lost performance on the cleaner. If so equipped, close off the bottom drain valve and increase the suction on the vac line. I can provide further details as needed, but will need more information from you regarding actual equipment layout.

With these pool cleaners, there are several things that it could be. Check the return line water flow and redirect as necessary with an eyeball diverter. Make sure the automatic regulator valve is installed properly and is not clogged. Make sure the cleaner has proper hose balance.
