It leaks a lot of water. I Checked the water container, the O ring seems okay. It does not leak by idle sitting but as soon as I make coffee the whole table is full of water.

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.

The cup warming tray works by sitting directly over the main boiler. If there is something wrong with the cup tray there is probably something wrong with the boiler.

If there is lots of steam coming from the top of the machine you may have a leak. Check for puddles under the machine as well.

Leaks
Coffee leaking into the drip tray could be from the brew unit or the front door assembly. Water leaking probably means a hose connection to the boiler has failed. Don't just leave it, fix leaks immediately. Besides the electrical danger, the rust on working parts from long term leaks can be extensive.

Are you confident? Operate the machine with all covers off to see where the leak comes from. Be extremely careful, ready to pull the plug at any moment. Touch nothing inside! Burning, scalding and electrified! Check both boilers very closely while making coffee, most leaks become obvious on close examination.

Most leaks are due to failed o-rings in the connectors at the end of the teflon hoses, usually at the coffee boiler. Replacing the o-rings should stop the leak.

Source replacement o-rings. Slide the hairpin c-clip out of the side of the white connector and pull the teflon hose out. Fish the old o-ring out of the connector with a small hook or point if it didn't come out with the hose. Place the new o-ring over the end of the hose, snug against the brass collar. push the hose back into the coupling being careful to go straight and true so as not to damage the new o-ring. Some force may be required, be careful not to kink the hose. Blunt needle nose pliers to push the rear of the brass collar usually does it. Replace the c-clip and test for further leaks before reassembling.

on a N95 fill the water container and take it off the machine if it leaks its just the red seal on the botton but if thats not it put the water container back on full of water,let it sit for a bit,it wil leak out the front or side it will be the dark grey seal in the base were the outlet of the water container sits in, I found this with vmine anyway,it was hard to see it leaking but was a pain in the but!! i will talk to Delonghi or pull the seal out and match one the same

Water container have a small valve which work with a small spring and o ring. You can remove the container over a sink unit fill with water and try to press with your finger to check if it block the water without pressing it and also check visual if their any dirt or scale blocking it from closing full or if the o ring is damages in any point.
In any case the valve work very simple the the spring force down the piston and o ring should block the water from ascape if any of thsi is dirty or damage or the loose then the water will leak.
You should also check the valve base on the machine body since their can be something that blocking the valve sit corectly on base so water can leak out of the piping arount the machine.
Good luck

The o-ring on the bottom of the water tank is either missing or not seated properly.

Hi
There is a donut like cap under the water tank on top of the machine. Pry on the outside of this cap an pop it off. Under the cap is a black seal. If you stick your finger in it and just pull out and the seal comes with it, you need to replace the seal. The new seal will not slip in you have to run your fingernail around the outside and silp the seal in. It should not just slide in. Make sure that the receptacle is clean before putting the new seal in.

I rang Saeco service centre about my leaking water tank and they posted me a new tank - no questions or need to return the faulty item. I believe there may be a bad batch of tanks which leak because of faulty valves.

You either have a small crack on the water tank and/or the connection from the bottom of the tank reservoir to the machine is not sealing properly. ( i.e similar to putting the tank on top of a flat surface, the tank will leak as the seal connections gets pushed up and water begins to flow out)- it is that component that I am refering to. If you can inspect it to pin point the problem - if the latter is the case (valve), could try purchasing a new o-ring, piston, and valve. Suggest contact

i got a vienna digital when i take the water container of to clean it 1 time out of 2 im gonna have water all over the floor what i do now clean the container put it back fill the water container with big glass and no more leak it probably have to do warp water container when it empty it seat perfectly when you have it in our hand it warp a little bit were not the only one with that me when i dont remove the container to fill it up i have no problem since then thanks for using fixya pierre

Saeco use the same seal under the grey plastic ring on most of their coffee machines so it should be easy to find a replacement from any Saeco, Spidem or Gaggia service centre.

In most cases the seal isn't worn, it just isn't sitting right, so remove the grey cap (two flat screw drivers to lever from both sides at the same time helps) and reposition it. This is usually all that is needed if the problem is only intermittent.

Also check that there isn't anything sitting in recesses where the legs of the water container sit. It only takes a tiny bit of dirt to stop the container sitting in far enough to seal.

However, make sure the leak isn't coming from the container itself. Hold the container up with water in it and see if it drips. Check the the spring is clean.
