Sprinklers not turning

Clogged nozzels ?

If the arm spins easily by hand, but won't spin when operating, that points to poor water delivery...
1) check the strainer. Not just the holey one you can see, but there might well be a very fine mesh filter under it ~ if so, remove it to clean it (it can appear clean, but still be clogged with transparent cellulose fibres). Try running the machine empty without the strainer/filter fitted. You should hear a difference if the filter was causing the problem.
2) you might have a weak impeller. After a while the plastic impeller on some machines just wears away, leaving insufficient fins to move the water, this can be accelerated by e.g. broken glass stuck in the pump. Impellers can also slip on the motor shaft; the motor's spinning but the impeller doesn't. This means removing the machine, turning it over and removing the pump for inspection...

Turn off the water supply to the sprinklers system.
Connect a compressor to the system and blow out the individual zones, one at a time.
You can have this done for you for about $75.00 if you are without a compressor or are unsure of the procedure.
Doing it incorrectly will destroy the underground pipes as the water will crack the pipes.

your sprinkler motor needs to be replaced. sprinkler motor is located right below the windshield washer reservoir

First you have to do is try the machine without load. Attach everything as usual but do not attach the lance. Put on machine with water supply already on. If you close the gun the machine should stop. If you open the gun ( always with out lance)....the machine should start sending the water a bit far. If this is OK....then you have a lnance with a faulty, blocked NOZZEL.
NOrmally the machine stops when gun is released because there is a valve (Spill Valve) that actuates a electrical micro switch. This in turn closes off te elecreic supply...stopping the machine.
If with out lance your problem is still there....then the spill valve is faulty. AS I first said you must be sure that the nozzel is OK, so that you can blame the Spill Valve.
I raely service Spill Valves (Control Valves). I change with a new one. When open the cover using a TORX T15 screw driver....you locate the spill valve where there are 2 wires coming out. Some machines have the spill valve incorporated with the head and the intake and delivery valves unit. This I advize to change with new parts. These all in one heads are very good because at one go you change the spill valve and the other valves in one go.
Therefore in a few words you either have a blocked nozzel...or you have the spill valve faulty.
Also the delivery valves could be blocked...thus creating pressure inside and activating the spill valve to close off the electricity. You can also try to start the machine without gun and hose attached...but always with water being fed. NEVER put on a power washer without water being fed. And never store a power Washwer withpressure in it.

So I advice again to try the machine with out the lance. If when gun is closed machine stops and stays that way ..it means the spill valve is doing its job. If when putting back the lance and the pressure starts to pulsates...the lance nozzel is faulty and thus causing simptyms on the spill valve. Also try to use machine with a new lance...having a new nozzel.

1. water temp must be 120+
2. soap must not be old
3. Machine must work as designed

place a cup upright on the top rack, run a few min. it should have some water in it.

Usually the spray arms are not turning with that problem. They are designed to turn by water forced out the end of the arm, much like a lawn sprinkler works.If the end holes are clogged, it wont spin. The arms should spin freely.Then check to make sure that the water didn't drain out as fast as it came in. Some D/W have a valve that will get stuck open and the water drains out during the wash cycle..no water, no wash..

i wouldbet it is a pressure related problem , can you isolate them so you are only running 1 at atime? at least reduce the number of sprinklers running at the same time just to test them, drop the number by1or2 and i`m sure your problem will be fixed youdoit

The small tank of water on left side fills up, but does not come out of the sprinklers to to wash the dishes.

Can you provide more information on symptoms: Does machine fill? Does water come out of the spray arms a) at all and b) in convincing quantities (part way through the cycle, switch off, open the door straight away and see what is happening inside). Do you get the same problem if you run the machine without any dishes in? Can the spray arms be turned freely by hand? Knowing the answers to these should help narrow the problem down. A.
