Sempre que ligo a maquina para retirar o cafe, noto que ela vaza água perto do reservatório de água. Já a desmontei para ver se havia alguma fuga ou tubo gasto mas não. Não encontro nada. Coloquei a máquina em funcionamento desmontada e o certo é que fica tudo cheio de água e continuou a vazar sem indícios de onde se encontrara a fuga.

Tenho uma cafeteira expresso MEGASTAR {IDÊNTICO a CAFETEIRA ETERNY CM 508; ZEEX MANUAL BUON PALATO CM 508; e o tal de HUAYU CM 508 - fotos anexas} com o seguinte defeito: pressionado a botão POWER o mesmo “não prende”, em função disso não aquece . . .

Resido em São Carlos-SP-Brasil, e, não encontro ninguém para fazer o reparo . . . Como resolver? . . . Podem me indicar alguma Assistência Técnica aqui no Brasil?

OU, fornecer desenho de montagem/componentes para viabilizar uma "desmontagem sem estragos"?

Na eventual falta de componente, concordo até com o “quebra-galho” de “ligar direto” {jampear} os contatos desse interruptor, adaptando uma “chave pera” no cabo de força, uns 15 cm da base da cafeteira – ai a liga/desliga seria feita pela chave pera . . .

Cordialmente,

Good afternoon . . .

I have an espresso machine MEGASTAR { IDENTICAL to ETERNY MAKER CM 508 ; ZEEX MANUAL BUON PALATE CM 508 ; and such of HUAYU CM 508 - photos enclosed} with the following error: Pressing the POWER button the same " does not hold " , because it does not heat up . . .

I live in São Carlos -SP-Brazil , and can not find anyone to do the repair. . . How to solve? . . . Can show me some technical assistance, here in BRazil ?

OR , supply mounting design / components to enable a " disassembly without damage " this machine ?

The possible lack of component , I agree to with the " quick fix " of "direct connect " { jumping } contacts that switch , adapting a " pear key " in the power cord , about 15 cm from the base of the coffee - ai league / off would be made by pear key . . .

Sincerely,

I found mentions of the motor not being properly aligned.

The official FAQ states: The motor might not be in the correct position. Check if the water tank is filled and if the drip tray is in place. Turn the appliance OFF and then ON again. Then simultaneously press the button for My-Coffee and the on/off button for more than 2 seconds. The motor will move into the correct position. Insert the brewing unit again and check that it is correctly locked in position.

However, this proposed solution did not reset the motor position in my case.

I found that the locking handle of the brewing unit moves a metal lever.

This metal lever engages a button in the machine.

By carefully pressing this button (i used the handle of a small spoon), the motor reset to the correct position.

Long story short: I don't have a question, and just wanted to post this here for future reference.

This is my third machine I’ve received from Keurig support and it’s still happening. I’ve done all the needle cleaning, reseting, descaling, and many other fixes. The unit is not even 3 months old.

I’m just at a loss of what to do because I don’t see many people having the same problem. I’m also sick and tired of wasting perfectly good K Cups! Anybody have ideas how to permanently fix this?

EDIT & SOLUTION: I've been able to resolve the issue using a work around. This is not a fix and I don't know why Keurig hasn't fixed it after years of this happening.

When using a milk based K Cup, press it into the bottom by hand so the K Cup is punctured. Pull it up and rotate 90º and close the lid. This gives the K Cup two holes and much less pressure. It has worked perfectly since I've been doing this.

I am troubleshooting a professional coffee machine (Melitta C35) control board based on the Freescale ColdFire MCF5232CVM100 (BGA package). The system is currently stuck at the initial "Please wait" screen and does not proceed to the main menu.

Hardware Details & Measurements:

·         MCU: MCF5232CVM100 (ColdFire V2 Core).

·         Flash: cFeon EN29LV160 (TSOP-48).

·         Power Rails:

o    VDD (Core): Measured 1.6V on the micro-capacitors surrounding the MCF5232.

o    VDDIO/Periphery: Stable 3.3V found across the board.

o    Analog/Other: 5V rail is present.

·         RTC Battery: Measured 3.29V (stable).

·         Debug Interfaces: The board provides a standard 26-pin ColdFire BDM header AND a 10-pin (2x5) Mini-BDM connector.

·         Service Port: External 9-pin RS-232 (DCE, Female).

Symptoms:

1.    On power-up, the display initializes and shows "Please wait".

2.    The board has a Reset button that toggles the 3.3V line, but the MCU remains in the same "Please wait" state after reset.

3.    I measured -5.6V on the TX pin of the RS-232 port, which indicates that the line driver is powered and the UART is likely initialized by the bootloader.

Questions for the community:

1.    Given that the display shows "Please wait", is it safe to assume the MCU has successfully initialized the FlexBus and started executing code from the external Flash?

2.    What are the typical reasons for a ColdFire V2 to hang at this stage? Could it be a checksum mismatch in the Flash or a timeout waiting for a peripheral (I2C/SPI)?

3.    Does the presence of both 10-pin and 26-pin BDM headers imply any specific debugging priority? Is one more suitable for a USBDM interface to dump the cFeon Flash?

4.    Are there any known "trap" states or Double Bus Fault indicators I can check via the BDM pins without a full debugger?

Thank you, Alex

Everything seems to work fine except for the steam.

It will produce hot water out of the water spout and will also do a full descale.

But when I choose the steam function or put the milk canister on it makes a funny noise like it has a blockage because when I stop it some steam comes out the back of the machine. I have always done the descales and changed O- rings when needed. Greased up the enfuser when was getting stuck, that fixed that. Put rubber grommet in suction straw on the milk canister that has a smaller hole in it to slowdown the milk feed so that it heats up more, got this from delonghi. Hot cuppachino now.

What do you think is the problem. Could it be the solenoid doing this.

The machine has a external push on water and steam spout.

This is the machine.

Also a milk jug.
