Does anyone know how to access the Service menu, and change wash & rinse settings on the W4842??? The instructions I have are for the W4840, and while the first part does allow me to access some menu on my W4842, these instructions are for the 4840.

While the washer door is open, hold down the PAUSE button. Close the door and then press PAUSE five times in quick succession, holding the button down on the fifth push. You will shortly see the service menu options appear.

Water+/Additional Rinse is on by default, so nothing to do there. You will want to turn on Maximum Water Level to get the high rinsing levels. Allergy function does nothing from what I can tell, and Rinse Process should be off because it will interfere with your maximum water levels set earlier.

With regards to shaking and vibration, something is amiss in your installation. If they are on pedestals, make sure the pedestal bolts are properly tightened. Sometimes the machine may appear level even if you use a bubble level, but one of the feet may not be making proper contact with the floor.

Update 05/21/2024: 32,137 cups brewed. The machine was struggling to push water through the brew unit. I purchased another water pump and that fixed the problem (see below on how to replace).This pump seems to have made at least 10k cups of coffee so not that bad. I took the old pump apart and there is not much to it.I found there are rebuild kits online that replace the plastic ball valve and o-rings. The next time it starts to be a problem, I'm going to try the rebuild kit (which is less than $10 dollars and is on eBay).It seems as though the better rebuild kits include a glass ball vs the plastic one. Here are some pics that show the potential issue of how the pump can wear out: pic1 pic2 pic3

Update 04/18/2023: 28,991 cups brewed. The coffee grinder started to sound like it was strained. Sometimes it wouldn't even start to grind the beans and only show the brewing animation in the LCD display. I thought for sure the motor needed to be replaced, but after taking it apart, it only needed to be cleaned.

To clean, you need to remove the top cover, remove the coffee bean hopper (put a tupperware under or all the beans will spill out), remove the coffee bean chute with the 3 screws and now you can see the grinder. To properly clean, you need to unscrew the grinder cone. This is a reverse thread. Carefully remove the parts and don't lose the the washer, springs and ball bearings. Detailed instructions can be found here. When reassambling, ensure to push down on the cone as you screw in the retaining screw. If not tightened, the plastic worm gear won't seat properly.

You can also test the grinder manually by going into service mode and pressing the small coffee button. This will manually turn the grinder so you can see if the motor is working at all. (check the link to the service manual below on how to enter service mode)

Update 12/30/2021: 25,315 cups brewed. Started randomly getting a BREW UNIT MISSING message. It would work sometimes if you really pushed in the brew unit and then finally wouldn't work at all. There is relay switch (XCG5-81-PS or XCG5-81-P5) with a gray lever that the brew unit pushes into to signal the unit that it's attached. The gray clip broke off the relay. To fix, I didn't replace the relay but simply connected the yellow and black wires to the two closest pins which basically simulates the button pressed. To get at the switch you need to: take the top cover off. Open the front door and remove the grinder. Lift it out the grinder assemble to the side. You'll need to remove a green wire, move the circuit board above and remove the sliding levers. Next loosen the various screws around the brew unit switch and gently push the plastic housing and you should see the relay switch. Another alternative is cutting the yellow wire which should fake the switch being closed.

Update 6/14/2021: About 23,849 cups brewed. Machine was descaled but seemed to get stuck in RINSING MACHINE mode. The fix is to hold down large coffee + small coffee + hot water and turn the machine ON. This will bring up the menu. Scroll down to Descaling. Click enter and that will switch it OFF and out of DESCALE mode.

Update 12/25/2016: Just a quick update. 13k cups brewed and going strong! If you are in need of parts, the Saeco Vienna Plus shares the same parts as this Miele CVA615. Here is adetailed parts diagramand an online place tobuy parts. Additionalpart diagrams. Just be careful and try to match it up with the original Miele part.
