There are 2 possible issues with this model. 1. There is a spout on the back wall which drips overflow into the drip tray, under the pod container, a faulty design which can allow some of the water to leak under. Adding a custom silicone seal there helps a lot: clean the back wall under that spout where the tray touches it with alcohol. Cover the back of the tray with cling wrap, well secures, and slick it with a very thin layer of petroleum jelly. Put a bit of silicone under the spout and along the line the top of that tray touches the back wall, and push back the tray in position, then wait 24 hours. Remove tray, wipe any excess petroleum jelly on your new custom silicon seal, which will now keep that overflow water correctly in the tray once back in position.
2. The filter in the brew unit, which pierces and filters the coffee from the flat end of the pod can become clogged with dregs and coffee oil. Increased pressure provokes the leaking, not a bad seal. First step is to repeatedly wash it with a toothbrush and very hot soapy water, then rince with a lingo cycle without a pod. Repeat. Repeat. Still leaks? If you have the tools for it, try forcing a reverse hot soapy water flow from the coffee spout in front to the filter part. You could also use descaling solution repeatedly as if doing a series of lungos instead of a full descaling cycle, waiting a few minutes between shots.
3. If all this fails, you can order a new Tmbu assembly (the brew part) and replace it. YouTube videos for the en750 model disassembly do exist. Requires good tinkering abilities.
Hope this helps.
