There are several reasons if spray arms doesn't spray water. First you need to check efficiency of circulation pump. If it works, then should check the turbine of circulation pump. Sometimes turbine blades can be broken and the pump does not produce enough pressure to turn the spray arms. Be sure to check that the filter is not clogged which can also causes same problem. Finally, check that the nozzles of spray arms are not clogged.
So, could be:
- motor circulation pump
- circulation pump
- spray arms
- electronic or power board
I have a small stream nozzle on my hose that puts out a good but of pressure. I turn the filter bag inside out and spray it til it's white. I then turn it back in and spray water from the inside out. The bag is also machine washable if it still isn't clean.
It would help to identify the Brand of product. Check your wand stem. Most wands have a filter inside to keep the spray nozzle from clogging. Some Brands have filters just inside the coupler to the water source. Most of these screen filters just pop out for cleaning.
Sounds like you need to change the fuel filter.Use a piece of tie wire with hook on one end and fish out the plastic tube with the fuel filter on the end. Hemostats can be used also.Use a turkey baster to **** the gas and trash out of the tank.then pour in a pack of BB'S cover hole and shake the saw.This will loosen any stuck trash and when you put some gas back in it will come out with the turkey baster.The next step is buy a spray can Berrymans carburetor cleaner (any carb cleaner will do.) I recommend saftey glass's for next step.Stick the carburetor cleaner nozzle straw in the tank tube and press the saw trigger like you were going to cut wood,spray cleaner and open and close saw trigger 4 or5 times.If you do this with the carburetor filter off, place a clean rag over the carburetor.When you think it's clean hold the trigger open until the cleaner dries and then install gas tank filter.Now spray carburetor and linkage on the outside.Install clean filter and cover.With new gas&oil mix in tank You should be set to go.If this is not the right solution please post again.Thank You for choosing FixYa.
Take the top cover off of the unit. Plug it in and look inside the burner can to see if the ignitor is glowing. If not you probably need an ignitor. You can remove it to check the heating element to see if it is intact, but be very careful, it is more fragile than glass. If it is intact, you may have a control board issue. The ignitor should glow before the fan starts. Be careful to stay away from the fan blades while doing this. If the ignitor glows, and the motor starts, you should then be able to see fuel spraying out of the spray nozzle. You may need a flash light. If the fuel does not spray out of the nozzle in the correct amount, the unit will shut down. There is a photo cell that detects ignition. If the fuel pattern does not look even, you could have low air pressure out of the pump, a dirty fuel nozzle, or a plugged fuel screen inside of the tank. The air pressure comes from a pump on the back side of the blower motor. Insure that the filter are clean on the pump; there are three of them, and the plastic end cap needs to come off to access them. If they are dirty, they need to be replaced. The air pressure off of this pump is very critical to proper fuel delivery. The rated output pressure of the pump is on the heater data plate. You will need a low pressure air gage to check this pressure. Another source of low air pressure is the plastic end cover over the filters. They tend to crack with age. Spray soapy water on the end cap while the blower is running to look for leaks.
Yes there is a filter. Pull up on the fuel line, or the rubber grommet that goes into the tank with the fuel line through it. There were different types of filter used. One is inside a black plastic tube. You can pick it out of the tube with a pick. Another style is located on top of the tank and is of white plastic. Your fuel delivery problem may be air related. The air pump is on the back of the blower motor, and meters a set volume of air to **** the fuel out of the tank and blow it through the nozzle. This air pressure is stated on the data plate on your heater, probably about 3.6 psi. The air filters on the air pump could also be dirty causing the air output to be reduced, and thus low fuel flow. Also check for air leaks at the pump. Spray soapy water on the black plastic cover and look for bubbles, which are of coarse air leaks.
Make sure that the ignitor is in the mist of atomized fuel. Or better yet do you have signs of fuel atomization? Check fuel filter usually an in line transparent type filter, if it is clear check the nozzle they have a screen inside as a filter as well no fuel there lines to the tank are next in line if you have fuel up to the nozzle it may be time to replace the nozzle sorry but you can not clean them any slight bend or widening of the holes changes the rate of the nozzle. Pay attention to the GPH rating and spray angle when replacing the nozzle.
This sounds as though the pump belt is slipping and burning. This may be caused because the pump belt has stretched slightly or the pump is seized and will not turn. Remove the pump belt and turn the pump rotor with your fingers to see it turns freely. If it does then the pump should be OK but the belt may be stretched and will need replacing. If the unit does not spray after changing the belt then clean the spray nozzles at the front of the machine and make sure that water flows to the nozzles OK. You can check this by temporarily disconnecting the nozzles from the plastic pipes.
Main causes for no spray.
Bladder may be empty. SmartMix Bottle may be empty. The Filter may be clogged. Tanks may not be seated properly. Pump may have lost prime. The Pump Belt may be broken.
