Question about DeLonghi Coffee Makers & Espresso Machines

1 Answer

Delonghi Magnifica won't brew or rinse

It generates water or steam through the want which (I think) means that the pump is working and that the heater element is working. At times, the grounds are damp if I try to brew coffee. The rinse cycle doesn't run any water through. I've decalcified it and I've taken the infuser apart to verify that it isn't clogged. I've also pulled the heater assembly (heater and the attached yellow plunger) out and cleaned that as much as I could although I did not clean inside it. I'm stumped;( I got this used at an auction so I don't know any history about it. This is a 120v unit - some things talk about a 220v unit - don't know if that matters or not.

    I don't see an option to edit a question so I'll just add a comment.

    OK, I'm new at this - anyway, I realize it's a steam wanD, not a wanT;)

    But, that's not my main comment - under the heating element, there is a generator assembly (I think that's what it's called). In there is a valve. I believe the valve pin which rides on a spring wore down and shoved into the valve pin. I think if I get a valve pin and valve, I'll be able to fix this thing. I'll probably order parts from

Sounds like the pump or its internal valve are not working. Check for voltage with a multimeter at the pump when it brewing. If voltage is present likely the pump has failed. Also check hydraulic pipes are clean and clear and that any filter screens are not blocked by scale.

    It was the valve. The pump was working and I had descaled it. I basically tore the whole thing down and inside, I found the valve and valve body.

  • jerry shenk Dec 13, 2014

    Ah...bumped enter. Anyway, the valve is a little rubber piece it it looks like it wore down to the point where it shoved into the valve and blocked all flow through the infuser although it still allowed water to pass to the steam wand. I got a new valve body and valve for $4.41 each - probably wouldn't have needed the valve body itself but, I wasn't sure and for 4 bucks, I decided to order both. Had an espresso this morning!!

    Glad you managed to fix it, and pretty cheaply too.

SOURCE: DeLonghi Magnifica always asks "Insert Infuser Assembly"

on my machine, the two screws that attach the infuser receptacle to the insides of the machine came loose. You can see those two stainless hex socket screws when you remove the infuser by grabbing its two red tabs and pulling it out. Just use a hex shaft
screwdriver (size 3mm or thereabout) to tighten them.

SOURCE: Saeco Vienna Deluxe starts brew cycle then red light comes on

I think you put the tubes on backwards to the flow meter. The inlet side of the flow meter is by the pump and the exit to the pump is by the water tank. They cross.

SOURCE: When brewing, it steams and spits the water out

this is what happened to me, I didn't have the filter basket all the way down so the pot lid didn't open the valve that lets coffee flow so the coffee and grounds ran into the water resevior and plugged the filter, so I did the worst thing possible and took the filter out so the grounds got into the check valve that keeps the hot water going in the right direction. that makes it spit and sputter and brew slow.
after trying to flush it out forever I tore the metal plate on the bottom off and unhooked the rubber hoses (don't do this unless you have a needle nose pliers, you'll never get them back on) one should go to the brew head and the other is the water inlet, this has the check valve. you can tell which is which by blowing through them and seeing which one goes to the brew head. if you can blow through the other one the check valve is stuck open, I blew air into it with an air compresor and this forced the check valve shut and now it works fine. I know this is the same symptons as calcium deposits but I had cleaned it twice.
try flushing it with water first but sometimes it takes extreme measures

Mr Steam MS Super-1 kW: 10 doesn't generate steam

the first thing the generator should do when you hit the on button is fill. You will hear the water entering the tank. Once the water stops it indicates that the water has reached the water satisfied level, after which you should hear a loud click(your contactor engaging for the heat cycle, newer units will have all three light on the side lit). After this point is you aren't getting any steam after 5 minutes it probably means your heating element may be damaged. It would be best to remove the element at this point from the left side of the unit via 6 bolts and 2 wire leads. Any physical damage on the element such as a pinhole pop, burn mark, melting, or scar will surely prevent the element from heating

Shark steam mop not producing steam

It is a design flaw having a check valve orifice built into the steam generator.<br />The plastic sleeve gets hot and get hard and shrinks enough to cause blockage at the inlet to steam generator.<br />Also a lot of sediment builds up inside steam generator from impurities in the water which eventually causes a problem and block at the mop head.<br />solution would be to move the check valve from the steam generator to the pump discharge line where it is cooler. and use only distilled water. they should also use a stainless heater element instead of pot metal as it corrodes.<br />

You would need a multi-meter or voltmeter to trace the power path. Turn on the generator and wait until you hear the water feed solenoid stop. This means the water has reached the satisfied level and the pc board should have sent 24v to engage the contactor. On the actual pc board there is a section label "cont" which is what sends the 24v to the contactor the engage the heating element. Verify that you have 24v on the spade terminals going out to the contactor, if not then you may have a pc board issue. Second possibility is the contactor, if it is recieving 24v and it is not engaging then it's simply a bad contactor. Check the load side of the contactors with the blue wires. Lastly if these two steps check ok, then perform an ohm reading with a multimeter on the actual heating element(with the power off, put your two test leads on the two flathead screws that hold down the blue leads the go to the heating element). If you get an open reading then this may indicate a failed heating element. Pulling the heating element out on the left side panel will confirm any element failure.

No steam H2O comes up on the control screen

Water isn't getting to the H20 sensor. Try running some vinegary through it. Water will leave mineral deposits after is's been in use for a long time or has been stored with water in it that has evaporated.Check all hoses running from water tank to the heating element.

I have a front load LG washing machine. Its two years old and it stopped working today and it is giving a code of TE on the read out. what does this mean? Any help would be greatly appreciated!

TE is a Thermistor error.

This can be a shorted Thermistor and or a bad heater element. These items are located at the front bottom of the washer's tub.

If you have a washer with steam function. It could also be the steam generator's thermistor and or a bad heater element. The steam generator is located just behind the dispenser’s housing on the top left side.

I can get you part numbers is you need them.

If it leaks from the steam wand then you need to get a new steam valve assembly. For the heat you will have to open the machine it is possible that the steam boiler is damaged or that the thermostat on there is bad, use an ohmsmeter to check thermostats and element. There are 2 screws in the grinder, 2 behind the water tank and about 2 or 3 in the front behind the door.

Makes espresso, coffee, water, but will not steam

The pump has gone bad - through use. This is a common problem, and has to do with the "seals" that are in the pump. Since the pump generates high pressure and heat, over time, the seals will fail, and will be unable to generate enough pressure and heat to create steam. The only remedy is to have the pump replaced through the Breville Out of Warranty repair centers.
