Long Term ( 3-4 day ) Tank Leaks From Rear Vent Holes

If your Nespresso D150 coffee maker is leaking water from the bottom as soon as you attach the water tank, there might be a few possible causes for this issue. Here are some steps you can take to troubleshoot and address the problem:
1. **Check O-Ring Seal:** Even if the O-ring inside the water tank appears fine, it's worth inspecting it closely for any signs of wear, damage, or misalignment. If the O-ring is not creating a proper seal, it can lead to leaks.
2. **Clean and Lubricate O-Ring:** Sometimes, debris or residue can accumulate on the O-ring, preventing it from forming a tight seal. Clean the O-ring and the area where it sits in the water tank thoroughly. Applying a small amount of food-grade lubricant can help ensure a proper seal.
3. **Check for Cracks:** Examine the water tank for any cracks or damage that could be causing water to leak out. Even a small crack can lead to significant leakage.
4. **Check Water Tank Connections:** Ensure that the water tank is properly aligned and securely attached to the machine. If it's not properly seated, it can cause leaks.
5. **Inspect Machine Gaskets:** There might be gaskets or seals on the machine itself that interact with the water tank. Inspect these gaskets for wear, damage, or misalignment.
6. **Water Level Sensor:** Some coffee makers have a water level sensor that detects the water level in the tank. If the sensor is damaged or not functioning correctly, it might cause leakage. Contact Nespresso or a professional technician for assistance with sensor-related issues.
7. **Pressure Relief Valve:** Coffee makers often have pressure relief valves to regulate pressure within the system. If this valve is not functioning properly, it can cause leaks. This might require professional assessment and repair.
8. **Contact Customer Support:** If the issue persists despite troubleshooting, consider reaching out to Nespresso's customer support or a professional technician who specializes in coffee maker repairs. They can provide more specific guidance based on your machine's model and issue.
Remember that working with electrical appliances and water can be potentially hazardous. If you're unsure about any aspect of troubleshooting or repair, it's best to seek professional assistance to avoid causing further damage or compromising safety.

Could be either one or a hose at is leaking. I check for leaks using a paper towel and wiping areas I suspect are leaking.

Hi rdavis_sf,

If you're encountering leaks under the tank, most often it occurs when the water tank is not seated properly allowing water to drain out of the tank and into the base.You can easily fix this by following the steps below.

1. Please remove the water tank.

2. There is an access opening like a round hole in the base beneath were the tank fits into the machine.

3. Using an absorbent cloth material dry the water through this opening. Please be patient, it can take sometime.

4. Once the water is gone the machine will operate normally again.

There are alignment pins on the tank that fit into holes in the coffee machine. Make sure this alignment holes are clear of any debris. Coffee beans have been known to make their way into these openings. Please use a flashlight and a small mirror to see down into the alignment holes.

Hope it helps.

Thank you for using FixYa.

Remove the bar and chain, then clean the entire area. Look for leakage at either the small port where the bar fits, or from the motor case itself. Make sure the oil tank vent is open so that pressure doesn't build up from heat. If the leakage is from the case, then look for a crack in the oil tank, or a defective oil line from the tank to the oil pump. Clean the drive end of the bar oil-channels that go out from the large holes to the chain groove on each side. Clean the entire chain groove. It also may be easier to just dump the oil out of the tank after each use if the chain seems to oiling properly. Hope this helps!

I have had the same problem. In my case, its the little water tank behind the left crisper. The tank has cracked (twice now) which means replacement (again). The water leakage gets so bad that it leaks into the freezer causing ice up problems in the rear.

I don't know what kind of toilet you have, but if it has a tank, then probably the tube that squirts water down the pipe into the bowl has come out. Take the top off the tank and as you watch, flush the toilet and make sure water is going thru the tube down into the pipe. good luck

It sounds like the new gas tanks do not have a breather fitted to them.

As you remove gas from the tank it needs to be replaced with air if not it creates a vacuum and natures way of filling a vacuum it to compress the space it is in

Fill a plastic soda bottle with fairly hot water , give it a minute then pour the water out and quickly screw the top on , watch the effect , that is your gas tank

There is either a metal or rubber tube or even a vent in the filler cap to allow air in

You did something to alter that ?

have you replaced the bleeder screws? and the expansion tank cap they both have O-rings that compress and will fail over time also check the hose at the top of the exp tank it also has o-rings inside it

Hi!

You Need to check the following--

The fill hoses : These are located behind the washer and are connected to the water mixing valve and faucets. Pin holes and cracks on the hoses may cause them to leak.



The water valve: The water mixing valve is located behind the washer. The fill hoses connect to the water mixing valve. Inside of the valve is that the water gets directed to the filling spout. Water leaks happens when the valve develop pin holes or cracks. Bad fill hoses or water valve could be the reason why the washer is leaking water.


The Filling spout: Is just a directing part, this part directs the water from the water valve to the tank. Pin holes and cracks is what make this part to leak.


The tank : The major cause for the tank to leak is through holes or cracks that the tank develops because of vibration or metal items hitting the tank during the spin cycle.


The tub seal : The tub seal is made of rubber, it is connected between the transmission post and the center of the tank. Leaks developed when the seal gets worn out and it looses the ability to make a good seal between the transmission and the tank. A crack tank or worn out tub seal could be the reason why the washer is leaking water.


The overflow tube : This tube is use to direct the water away from any electrical parts like the motor in case of an overflow cause by a bad water mixing valve or bad water level switch.


The pump : The pump job is to remove the water from the tank to the drain pipe. This pump has an electric motor and an impeller. When the pump motor is turning, any water that falls in to the impeller, is push out to the drain pipe.

Most leaks are cause by a worn out seal between the front pump housing and the rear one.


The drain hose : The drain hose is made of hard plastic and some times it develops pin holes and cracks leaks. Bad pump or drain hose could be the reason why the washer is leaking water.
