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

If the water has been sitting in the reservoir for days without use, it may develop a film on the ultrasonic element which inhibits the creation of the mist to come out the top of your humidifier. I would lift off the tank and empty the reservoir. Then VERY GENTLY with a piece of paper towel, wipe the ultrasonic element (looks like a disk the size of a quarter at the bottom of the reservoir) to clean off any film. Then replace the tank and let the reservoir fill up the tank and try it again. Good luck thebqe

You have a short. This is either from a bad cable or a faulty price of gear.

to find the problem do you want to isolate pieces of the system. Turn on just your speakers (if they're powered) or amps (if the speakers are not powered). With the mixer off, if you were getting a pause the short exists after the mixer. No buzz? Great! Turn the amps or speakers off to prevent popping. Turn on the mixer, and then turn on the speakers or amps. If you have a bus now with all channels on the mixer down it is likely your mixer. If there is no buzz, Bring the channels up one at a time. Once you find the buzz, turn the channel back down and plug unknown working microphone and cable into its channel. If the Mike buzzes when you bring the channel up it's the channel on the mixer. If it does not then the issue exists before the mixer. This is most likely and also the least expensive to resolve. Check the snake if you have one and all cables in line in a similar fashion. Most likely a snake channel has failed, you have a bad cable plugged in the snake Or you have a bad DI box or mic plugged in.

Happy hunting

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.

change the filter and check for fan moving to circulate the air in the unit

If you are trying to descale it of all the mineral build up. The easiest way is to mix a 50/50 1 gallon solution of Distilled White Vinegar and Bottled Distilled Water and pour it in the empty tank. Allow it to sit for a couple of hours (Longer if it's really scaled) . Then turn it ON and run it, until the tank is half empty. Then empty the remaining solution and fill the tank with Bottled Distilled Water and run until it's empty. In the future, it's better to use Bottled Distilled Water, rather than tap water.

Hope this helped you and thanks for choosing FixYa.

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 woodinvirginia

Since the unit is "almost new", contact the customer support phone number in your Owners Manual. This way, it's covered under the warranty.

If your "tap water" is from a well, the humidifier may be clogged with mineral scale. Even if it is not well water, your municipal source may have a high mineral content.

Using a 50/50 solution of White Vinegar and water run through the system will usually clean the mineral scale out. In the future, I would recommend that you use Bottled Distilled Water. You can buy it by the gallon, inexpensively at grocery stores or pharmacies.

The humidifier has a float valve in it much like a toilet tank does. If the water gets to low, the float valve should allow more water to enter the tank automatically. When it reaches the proper level, the float valve stops the water. The water line (either copper or plastic) coming into the humidifier should have a shutoff valve on it. Make sure that it is turned on.

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.
