Question edited for clarity, 'make model (what it is)'.
Question moved from Cars and Trucks.

You will only get that information direct from the company. There is no schematic and no repair manual. They are a disposable item when they break.

is the rubber seal in place on the cap or did you lose it could be a small crack where the threads are look for both , good luck

You either have a locked pump, impeller or stripped impeller on the pump shaft. Remove the jet pump assy and repair the pump and or impeller. You can also replace the pump assy.

Blower motor went out and blew fuse. You will have to replace the blower motor.

Hard water will build up on the rubber plunger casket and the beveled edge were the plunger seats in the cap, if you clean both pieces it will seat it self again

after scouring the INTERNET AND FINDING PLENTY OF SITES THAT WOULD SELL ME THE WHOLE CAP FOR 24.00. I MAD MINE USING SOMETHING FROM ace hardware THAT COST 2.50 Small suction cups with the hook [CDBL-7500S11] PART NUMBER 7500 .CAN BE MODIFIED INTO MAKING YOUR OWN GASKET. IT WORKED FOR ME ..REMOVE HOOK FROM SMALL SUCTION CUP. cut off nib with sharp pair of scissors. THEN DRILL HOLE THROUGH CENTER OF CUP WITH 7/64 DRILL BIT. re insert plunger part of cap through cap with spring and re- attach suction cup instead of gasket. MINE WORKS FINE ON A HOLMES 3700

When this happened to me, I took the tank into the bathroom to look at the bottom and then I tried to turn the knob and it wasn't all the way tight. After I tightened it, I put it back on the base and the mist started right away.

Mine dried out too. I could not find where to get the rubber valve seal for the tanks. Holmes does not list the part and when I called the rep told me they didid not stock the part. I solved my problem by purchasing thin rubber washers from Lowe's. They are 3/16 X 1 1/4 X 1/16 thick. The 3/16 hole in the center "snaps" on over the end of the plastic plunger just like the original. I had to trim the outside diameter with scissors to about 1" or using the old ones as a guide. Cost me $0.67

Mine did the same, I cut one out of a piece of inner tube rubber. It has worked just fine for two seasons.
