How do you get to the float sensor to clean it on dmt3000rfb

Try cleaning the intake valve as it sounds like it is stuck in the open postion despite the float sensor

if you have gas to carb rebuild carb or relace

There is a sensor that need to be cleaned if the code will not clear. I believe there is a black float that is part of the fuser bottle. If you swing out the oil bottle and look where the float would be... There is a sensor, clean the sensor and make sure it is plugged in correctly... Good Luck

Hi,
There is a float sensor in the washer fluid reservoir, if you could get that sensor at the top of the reservoir( where two wires is connected ) without pulling down the reservoir assembly, do it.
That float sensor might be stuck to " LOW " position that's why it lights up in your gauge panel. Clean and wash by using any ordinary laundry soap, play the float up and down just to be sure that it can fully slide on the guide rod.
If you cant pull or get that float sensor, you have to pull down the entire reservoir, so you could pull out the sensor, eventually clean everything, even the reservoir itself.
Hope that helps you out.

Hi,
The brake light is a warning that your fluid level is low. Check the brake fluid reservoir if the fluid is in minimum level. If the level is okay and it is full, the problem would be float sensor in the reservoir.
Please check the connector of the float sensor if it is connected and try to clean the metal pins( might be full of dirt and grease ).
The float might be stuck to "low" thats why the brake light up( move the float up and down to free it ).
Hope that helps you out.

Pull off the float bowl. Clean the bowl and bowl nut. Also in the threaded are where the bowl nut screws in there is a fuel jet / orifice with a tiny pin hole in it. If you have a inlMake sure that pin hole is clear of debris. Pull off the hose going to the carb and make sure you have good fuel flow to the fuel manifold. If you have poor fuel flow check the in line filter and the fuel tank exit port for debris. Use carb cleaner to clean fuel passages. With the float bowl remove the the main fuel line disconnected shoot carb cleaner from the float needle to the fuel hose connection and then from the fuel hose connection to the float needle. Reinstall the main fuel hose, float bowl and nut. Check for leaks BEFORE switching on the ignition.

Additionally make sure the engine Oil is serviced correctly. There is a low oil sensor that will kill the ignition if the oil level is low. For trouble shooting only you can disconnect ONE wire and check spark. If you did not have spark with the oil sensor connected and you have spark with it disconnected then the oil level sensor is either working correctly sensing a low oil lovel or... it is dirty and needs cleaned.

This SHOULD get you up and running again. If not just respond here with your ENGINE number and I will help you

Hi and welcome to FixYa, I am Kelly.

I note that your question was 3 months ago. I answered a current post today that had your exact same symptoms. Your post was revealed after I answered the current post. Had I seen your post 90 days ago I would have responded with the same answer as follows:

There is a low oil level sensor on the opposite side of the engine as the oil fill / dipstick. The next time that your presure washer acts up disconnect ONE wire to the oil level sensor. On pressure washers mose engines have the oil level sensor removed for just this reason. You tip the engine to move the power washer and you can not start it or.. if you move it with the unit running the oil level sensor kills the ignition. Just make sure that anytime you are going to use it that you ensure the oil level is properly serviced. (Each use)

There is yet another possibility. Debris in the bottom of the fuel bowl will draft directly into the lower fuel jet (Located inthe bowl nut area) with a tip of the unit and clog the fuel nozzle. You can prove you have a fuel problem simply by adding gas to the carb throat with the air filter removed. If you get a brief start... you have a fuel not a spark problem. Turn off the fuel selector... remove the fuel float bowl nut and drop the float bowl. Use carb cleaner in the threaded area to clean out the orifice in the body of the carb and then remove the debris from the float bowl. CLEAN the bowl nut also.

Use a spray can lid for the next step under the float bowl area.
BRIEFLY
Open the fuel selector and gently lift the float to level. Fuel must shut off when near level and re-start fuel flow as you lower the float. The spray paint can lid should fill up in 8 seconds or less. If you have poor fuel flow start looking at the bottom of the gas tank or an inline fuel filter as the problem. Some fuel selectors have tiny bowls under the fuel selector lever. Make sure to clean this out also if you have one.

Turn off the fuel selector. Reinstall the float bowl making sure the rubber bowl gasket is fitted properly. Fuel selector ON... leak test. Then test start the unit and see if your symptom is gone.
One more possibility. Your engine has and E-Z start valve that is supposed to be a compression relief. If this is sitcking / partially open ect.. it can make it hard to start your engine.

I really think you have a low oil level sensor issue that is grounding out the spark because it cycles to ground when you move the unit and is not... sensing the oil level properly after you move the unit. I clean oil level sensors with carb cleaner. You can wake up about 75% of them just by cleaning them off internally through the 2 side holes cleaning up to the contact area on the top of the sensor.

I had this same problem. The dryer would turn on for a few seconds and I could hear the water pump working followed by the "clean filter" light. This dryer has a float sensor which detects whether the pump is successfully getting rid of the condensed water. The only problem is that lint and other particulates condense out in the water and over time the float sensor gets stuck in the up position. The Ariston call center explained that the float sensor can trip the "Clean Filter" light.

In any case, the float sensor is located in the back of the dryer where the pump outlet tube comes out (when facing the back, it is in the lower right). I had to take apart quite a bit of the dryer to get access to the sensor. I ended up taking the near side off to release the plastic snaps that hold the cover over the sensor.

To fix the sensor, all I had to do was clean out the "bath" that the sensor floats in. And then figure out how to put it all back together.

The float switch is a proximity sensor. There's a float in the tank that triggers the notification when it leaves the proximity of the sensor, located on the right side of the tank cavity. Try cleaning everything and make sure the float is moving freely in the tank.
