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.

    I found cracked hose sections going to my barracuda that were sucking air. The barracuda was getting stuck on the drain, in corners, etc. Changed out the bad sections. Both the air accumulation in my leaf basket and the sketchy-ness of the barracuda stopped. Works great!

Pool cleaner starts and then stops working

Check for water flow / water flow restrictions / and water flow blockages.

Many things create water flow reductions: Dirty filters, plugged impellers, packed with debris baskets - both skimmers and at pump, closed to partially closed valves, air suction leaks: worn shaft seal, worn orings at pump lid or pump volute body, low water level, stuck skimmer weir blade/gate in the up position & skimmer empties and air is sucked into the system which may cause the pump to lose prime. This a problem that goes un-noticed and is hard to detect even by some service technicians!

Bubbles from water return inlets

its not uncommon to get some bubbles when using sectional hose as there are 12 connections that must be tight (but usually leak a bit). if you have access to a regular one piece hose, try using that to see if the problem corrects.
these machines are horrible for diaphragm problems which is why there is usually a big bin of replacements at every pool store. even though there is no tear, the rubber may have stretched or become rigid (water balance causes this)

My pump is running but pulling no water from the pool. It ran ok for 1/2 a day but a lot of air bubbles into the pool. Now it will not pull water again.

First of do not let the pump continue to run with out pumping water, permanent damage may result.
A couple of thing could be your problem. 1-Make sure the basket in your strainer is not plugged up preventing water from freely flowing through it.
2-Most likely you are sucking air in from the lid on the pump where the strainer is, you may need to replace the o-ring(s) and be sure to get the waterproof grease from the pool store and lubricate the o-ring(s) liberally and try it again.
Good Luck

My barracuda stops moving

There are several steps that you want go through to find the problem with your automatic pool cleaner. Check for air in your system, including hose connections, all fittings at the pump, checking the gasket in pump basket for wear.Make sure that your filter is backwashed and your pump basket is empty. Make sure that your main drain is closed and use your water flow gauge to make sure that you have enough water flow. Finally, check the diaphragm for wear and tear and replace if necessary

My barracuda g3 barely goes around the pool and also keeps stopping completly I have taken it to my pool store but they coldn't find anything wrong ith it.

If a store has check the actual pool cleaner for damage and couldn't find any, it is either going to be the connection or the water flow through the cleaner that is causing the lack of motion. Make sure that all of your hoses and connections are tight and secure with no cracks. Air getting into any of the lines could cause problems. You will also want to use your water flow gauge to make sure that you are getting enough water pressure to power the cleaner.

I have a Whiperflo 3hp pool pump. The water

There are a couple things that you will need to check when pool pumps start losing pressure. Air bubbles are definitely one step, but check these things as well. Check you impeller to see if there is a clog or obstruction. You pump strainer could also be clogged. It could be that your o-ring needs to be replaced also. Try these things, reprime the pump, and see if it maintains pressure.

I loose discharge water flow after about 5 minutes of running perfectly. The pump has no air bubble and is trying to push water thru filtration system ( if I open the backwash valve I have very good flow...

If you have a pressure gage it would help .. if the pressure is high then there is probably an obstruction in the return pipe to the pool .. if the pressure is low then there is most likely a restriction in the supply or suction side of the pump .. this would seem more likely to me from your description, there may be something obstructing the flow into the pump, a clog, a collapse hose from the suction, some flap of pool liner .. something like that ..
