Airless and HVLP sprayers..problems

[Teckel]

Hello guys.
I have an airlessco lp400 airless sprayer. Problem with this is that when I switch it on the motor will give a bit of turn and then stop. Anybody have an idea as to what the problem is??

I also have an accuspray 10 hvlp spraygun that is leaking at the back of the needle housing in front of the trigger and is leaking out onto the trigger. I took this apart and changed o rings and its still the the same. Any idea as to how to repair this??

Thanks in advance
Teckel

You may have a blockage in the pump which is why the motor is cutting off.

Thanks Dibs for your reply.
I took it apart right down to the piston and gave it a thorough clean. It's still the same as regards the motor cutting out.
Would it be electrical??

Can you disconnect the pump's drive from the motor and see if the motor will run by itself?

hi
Have you checked the plug, wireing for any loose bits / brakes.

It appears to have a brushed motor. Have you checked the brushes, as per page 15 of the below,

Sorry, no help to you, but just a quick 'heads-up' regarding sprayers.

I've just bought the entry level Earlex Spray Station from Amazon (as new £34 inc del). Wasn't expecting much, but very happy (and surprised) with the results. I've got 8 6-panel colonial doors and 9 louvre doors to paint (eggshell) and this is now a pleasure rather than a pain.

I have checked brushes and plugs. Any connections that I could check I have.
Beats me now anyway!!

Most likely a fault with the PCB as shown in the manual - in the electrical trouble shooting section. Might be worth a call to them to find out the cost of a replacement PCB. Might not be as expensive as you think.

:shock: :shock:
Pressure sensor is €160+vat and a PCB is €320+vat

Proper toys aren't cheap! :wink:

p.s. The motor is DC - worth checking the voltage to the connectors is constant and\or check the PCB for dry solder joints or broken joints. Even a visual examination might show a problem.

It's the pressure sensor that is causing the problem. Any parts suppliers for airlessco over your way lads that might have this part at a good price??
Thanks
