  • Sunbeam EM5300 leaking issue SOLVED

    The good news is in the topic. I fixed our (second) leaking EM5300. The bad news is it was a nightmare repair and I couldn't recommend anyone try it unless you're a glutton for punishment.

    I will however point to the problem here give some very brief advise if you want to try.

    This was our second DM5300, we returned the first one due to the same issue after about 6 months. But eventually this machine also started to pool water underneath toward the back. This time it was out of warranty and so I decided to try and fixt it myself. I looked all over the internet for any advice or direction as to what was wrong. There was almost nothing on line, hence why I’m making this post. I eventually found one part seller saying the part linked below was the issue.

    https://www.needapart.co.nz/buy-onli...00160-10123490

    It’s only a $15 part which is great, but it’s 3-4 hours of struggle to try and replace the thing. You have to dismantle the EM5300 and that’s no easy feat. For starters there are 2 security screws that you can’t even see that go from up under the cover around the group head and they hold the top of the machine in place. They are a Y shaped security screw and you’ll need a long screwdriver to get to them. Aside from that there are around 20,000 other screws you need to remove. Honestly, this thing was never made to be opened.

    Once you do manage to get the top and back off. You’ll be able to find the problem as per below. You can see in the close up the part has buildup of minerals from where water has been leaking from it. On a scale of 1-10 this repair is an 8 or 9 in terms of frustration and difficulity.

        Postmaster this crazy site won't let me reply to your PM sorry. I keeps saying I'm "not authorised to make this post" every time I try to reply. So I'll paste it here.

        I had to move that solonoid (number 1) as you can't really get to the 4 way connector otherwise. I don't think I could have done it without taking the top off the machine. You really need that acess. I struggled with the top as I didn't have the security screwdriver. I was going to drill the two security screws, but they are set too deep to get to with a drill. In the end I used brute force and it eventually broke the plastic around the security screws. It hasn't been an issue putting it back together with out those two screws and you would never know. I think the job would be impossible without the top removed.

          Thank you. Just as I thought.
          I might have to do the same if I cannot get a Tri-wing Screw driver. I think that was the one as it suite a Y security screw. Thanks again. I had to log in to send you a pm​. I was given the machine and the fellow said if you cannot fix it bin it.

            I have a similar problem, but it looks like it is at the selector switch assembly, rather than the four-way connector.

            How did you know that the problem was the part and not the seals of the tubes attached to it? The clips holding the tubes in don't seem to apply a lot of pressure. How would you fix it if it was the seals?

            I ended up making my own tri-wing screwdriver from a 6mm hex key with a 150mm shaft - using a dremel (equivalent) to grind the three wings at the tip, which is flat (not pointed like a Phillips head) and has a diameter of about 2.8mm. Works fine, but I will replace the screws with ordinary screws when I put it back together.

              EM5300 DISASSEMBLY

              Others wanting to take the machine apart may be interested in my experience.

              To prepare the machine, I removed the drip tray, the bean hopper and the top burr of the grinder.

              It is worth noting that a lot of parts are press fit and so have to be pried apart, sometimes with a bit of force. (I spent a lot of time looking for screws which didn't exist.)

              This applies to the top and the rear of the machine.

              The top is held on by five screws. Three are at the top of the rear panel.

              The other two are the tri-wing screws which can be found on the underside of the grinder, in recesses either side of the grinder outlet. It is easiest to turn the machine upside down to get these out.

              The screwdriver needs a shaft of 15cm to clear the grinder shroud, with a handle of less than 8cm to easily clear the base of the machine. (A converted hex key is ideal for this.)

              Plastic prying tools should be used to lift the top from the rear forward, ideally pivoting on the front edge. I found this required quite a bit of force. Even with care, it may not be possible to remove the top without breaking some of the small plastic tabs.

              There are two switches attached to the top, which I found I could leave in place, as long as I was careful not to pull on the wiring.

              Taking the top off the machine may be enough to spot the source of a leak.

              But it is likely that you may need to get the back off to fix it.

              This will require you to take the base off the machine (three small and eight larger screws) to be able to access screws securing the two back panels.

              You may be able to take the main rear panel off without first taking of the lower rear panel, but I found it easier to take off the lower panel first.

              Four screws hold it in place. Two are at the rear of the chassis near the base.

              The other two can be found in square recesses in the power cord storage bay, where they are screwed vertically through the panel tabs into the chassis.

              This also requires some prying apart. It may be useful to loosen the screws holding the sides to the chassis adjacent to this panel.

              Removing this panel is necessary if you want to remove the coupling for the water reservoir, which is mounted at the bottom of the back panel. (I found I was able to remove the panel without taking this off, allowing me to test for leaks with the reservoir more or less in place.)

              Removing this lower panel also gave me better access to the snap-fit tabs holding the main rear panel to the sides, which allowed me to lever them open.

              However, before doing so, two screws on brackets at the top of the main panel needed to be removed, as well as five screws at the bottom. Of these five, three are within the power cord bay and two either side of it.

              I would be interested to hear about others' experiences and tips.

                Hi, thanks for your posts and great to see other people tackled getting this thing apart...
                ​​​​​​I had the same problem (once I finally got it open, it sat in the cupboard for a long while) and replaced the 4 Way connector.

                Unfortunately, on reassembly I have a little spring poppet (pictured) that I have no idea where it's from, can anyone tell me?



                I reassembled it without it but when I use the steam wand the steam comes out the drip tray and outlet at the same time, so I'm guessing this poppet is required? Or a solenoid might need replacing?
                The leak is now fixed at least.

                Any help would be greatly appreciated

                ​​​​​​Thanks!
