Question about Krups Palatino 905-42 Espresso Machine

1 Answer

No heating when I switch the machine on, it makes the usual noises (normal I presume) and right after that, the second LED starts blinking (waiting for the water in the boiler to heat up) I checked the heating element but that is oke.(measured it and connected it to the mains directly.(got hot). However, I dont get any volts from the electronics and I can't quit figure out how it is powered. ( I am a technician) hope you can help me. Greetings, ps, checked all the micro switches .

    I have the same problem - the unit never heats up as designed and indicated by the continuous blinking light. I have the whole thing apart looking for a thermal fuse. Can you give me some direction? I clearly see the steam chamber on the right and a separate heating element/chamber on the left. I identified an inline fust but I checked continuity and it was fine. WHERE IS THE THERMAL FUSE?

I woke up this morning to the same problem! I called my brother who has fixed these in the past and he said it's probably the THERMAL FUSE. Hope that helps. He said it's about a 20 minute project to replace the fuse.

Washing Machine will not start

either your door actuator is broken or the door switch itself. look at the door and see if the latch(actuator) is broken or loose. If not order a door switch. It can be changed easy if you remove the retainer from the bellows and loosen it from the front of machine.
Hope that helps

My nissan 95 truck won't start. the battery is ok. once it wouldn't start and i put it in neutral then back to park and it started right up. where is the neutral safety switch located? I heard...

I think your reverse to park trick was a fluke,, I assume it turns over but since it is a 1995 you dont have a OBD 2 in the vehicle.
How to pull ECU error codes for 87-95 Pathfinders and Hardbody pickups:


The ECU is under your passenger's side seat. You can gain access to it by simply sliding the seat all the way forward and removing the plastic cover from the ECU. You can also remove the seat if you want, it makes access a little easier.

The VG30i ECU's have a tiny toggle switch on the side of the ECU with a small snap-in switch cover that must be utilized to select the diagnostic mode of the ECU. The 4-cylinder ECU and the VG30E ECU has a slotted switch that turns 1/4 or 1/2 turn clockwise and counterclockwise to do the same task. Some early 4-cyl HB ECU's have the switch as well. In any case it will have one or the other.

For 4-cylinder:
1. Turn the ignition switch on, but do not start the engine. All of the lights in the dash should be on.
2. Turn the 'diagnostic mode selector' screw on the ECU fully clockwise. The check engine light will go out. Wait 5 seconds, then turn the screw fully counter clockwise.
3. The check engine light will then begin to flash the trouble code. (number of long flashes is the 1st digit, number of short flashes is the 2nd digit)
4. To clear all stored codes and turn the check engine light off, turn the screw fully clockwise while it is in diagnostic mode. Wait 5 seconds, then turn the screw fully counter clockwise.
5. To keep the codes stored, simply turn the key off as the check engine
light is flashing and the ECU will keep all stored codes and the check engine light will remain on.

For V6:
1. Turn the ignition switch on, but do not start the engine. All of the lights in the dash should be on.
2. For VG30i: There is a little plastic tab you pull off of the side of the ECU(facing the door). A small toggle switch is behind it with 2 positions, "ON" and "DIAGNOSTICS". Using a small screwdriver or tool, move it to the diagnostics position. The red and green LED's on top of the ECU will blink simultaneously. One time, pause, then 2 times, three times, pause...so on for each mode, 1 through 5. Mode 3 is the most commonly used mode and will yield the ECU trouble codes you need to figure out what's going on with your engine.
For VG30E with slotted switch: Turn the 'diagnostic mode selector' screw on the ECU fully clockwise. The check engine light will go out. Wait 5 seconds, then turn the screw fully counter clockwise.
3. After it blinks both LED's 3 times move the toggle switch back to the on position. After about five seconds it will start to output out the diagnostic codes as with the 4-cylinder ECU. Note each code as it is displayed, the red LED flashing once for 10's, and the green LED flashing once for 1's. Meaning: One red flash and two green flashes means code 12.
4. To clear the ECU of any trouble codes, move the switch to the "DIAGNOSTICS" position then back to the "ON" position and turn off the key.

ECU Diagnostic Mode Procedures
Mode I - Exhaust Oxygen Sensor Monitor
-----------------------------------------------------------------------
Use Mode I to determine if the Oxygen Sensor is functioning properly.

Warm the engine to normal temperature.
Run the engine above 2000 RPM under no load while looking at the ECU.
Make sure the GREEN LED goes on and off more than five times during ten seconds at 2000 RPM.
If the number of flashes are not more than five, replace the oxygen sensor. If the LED does not flash, check the sensor's circuit.


Mode II - Mixture Ratio Control Monitor
-----------------------------------------------------------------------
Use Mode II to determine if the air/fuel mixture is cycling correctly.

Warm the engine to normal operating temperature.
Turn the dial on the ECU fully clockwise (or if you have a switch, turn it on).
After the LED flashes twice, turn the dial fully counter clockwise (or turn the switch off).
Run the engine above 2000 RPM under no load while looking at the ECU.
If the RED LED blinks simultaneously with the GREEN LED, the air/fuel mixture is cycling properly.
If the RED LED stays off, the mixture is more than 5% rich.
If the RED LED stays on, the mixture is more than 5% lean.
If the RED LED stays on or off above 2000 RPM, complete the diagnostics before beginning repairs.


Mode III - Stored Fault Code Reporting
-----------------------------------------------------------------------
Use Mode III to retrieve all stored trouble codes in memory.
Use the above posted procedures.


Mode IV - Switch Operation Monitor
-----------------------------------------------------------------------
Use Mode IV to determine if the Throttle Position Sensor (TPS), Starter circuit and/or Vehicle Speed Sensor (VSS) are in proper working order.

Turn the ignition switch on, but do not start the engine.
Turn the dial on the ECU fully clockwise. After the LED flashes 4 times, turn the dial fully counter clockwise.
Make sure the RED LED is turned off.
Make sure the RED LED turns on when depressing the gas pedal. If not, check or replace the Throttle Position Sensor.
Make sure the RED LED turns on when turning the ignition key the START position. If not, check or replace the starter.
Drive the vehicle with the ECU unbolted and within view. Make sure the GREEN LED turns on when speed is 12 MPH or more. If not, check or replace the Vehicle Speed Sensor.


Mode V - Real Time Diagnostic Function
-----------------------------------------------------------------------

Use Mode V to determine if the Crankshaft Position Sensor (CPS), Mass Air Flow Sensor (MAFS) and/or Ignition signal are working properly.

Start engine.
Turn the dial on the ECU fully clockwise.
After the LED flashes 5 times, turn the dial fully counter clockwise.
Make sure LEDs do not flash for 5 minutes when racing or idling the engine.
If it flashes, count the number of flashes, turn engine off, and see the following 3 paragraphs. Perform real-time diagnosis inspection and repair or replace malfunctioning part if present.
if LEDs do not flash for 5 minutes, turn engine off.

If the RED LED flashes 3 times for 1.5 seconds, check the Crankshaft Position Sensor. Check the harness continuity at CPS when the engine is stopped. Inspect the harness for dust and clean if necessary. Check the pin terminal at ECU for bends and remove them as necessary. Reconnect harness and recheck continuity. During real-time diagnosis, tap the harness connector or component and check if trouble code is displayed. If so, replace terminal.

If the GREEN LED flashes twice-3 times for 0.5 seconds, check Mass Air Flow Sensor. Check the harness continuity at MAFS when the engine is stopped. Inspect the harness for dust and clean if necessary. Check the pin terminal at ECU for bends and remove them as necessary. Reconnect harness and recheck continuity. During real-time diagnosis, tap the harness connector or component and check if trouble code is displayed. If so, replace terminal.

If the GREEN LED flashes 4 times for 0.2 seconds 3 times, check the ignition signal. Check the harness continuity when the engine is stopped. Inspect the harness for dust and clean if necessary. Check the pin terminal at ECU for bends and remove them as necessary. Reconnect harness and recheck continuity. During real-time diagnosis, tap the harness connector or component and check if trouble code is displayed. If so, replace terminal.

Hope this helps...

New to expresso machine - Cuisinart EM100c

This is a very loud machine. Here's the normal operation: You turn it on, and wait a few minutes for it to heat up, at which point the heating light will go off. Then make sure the function knob is turned to coffee, and it will start brewing. At first, it will make a short (loud) sound and then stop for a second. The purpose behind this is that the machine is pre-wetting the coffee, so that steam can more easily shoot through it in a couple of seconds. Then the loud noise will start again and run continuously until you turn the function knob back to the center. So, the sounds you were hearing were normal. There is a delay between when you hear the sounds and the water starts flowing out. If the coffee is pressed down (tamped) too hard, that delay will be longer. Hope this helps. You made a much better choice purchasing this machine rather than the more expensive EM-200, in my opinion.

No Pictre, Flashing Power LED - Philips 42PFP5532D Plasma

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Stops while driving

this is usually due to a dirty throttle body. just beware if you do try to clean it you will need to preform the idle relearn procedure. this does work, ive done it personally.

A. Accelerator Pedal Release Position Learning Procedure.
1. Make sure that the accelerator pedal is fully released.
2. Turn ignition switch “ON” and wait at least 2 seconds.
3. Turn ignition switch “OFF” wait at least 10 seconds.
4. Turn ignition switch “ON” and wait at least 2 seconds.
5. Turn ignition switch “OFF” wait at least 10 seconds (how would you know if you get it right?)


B. Throttle Valve Closed Position Learning
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch is “ON”.
3. Turn ignition switch is “OFF” wait at least 10 seconds.
Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound (i never get this right because i never heard anything)

C. Idle Air Volume Learning (Throttle Position Learning)
It's best to time with a watch/clock.

1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Conform that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops
blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11 Wait 20 seconds
12Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications. (this is fine because SES light lets you know if you did it right the way it blinks)

Toshiba power led flashing yellow

This flashing LED usually means only two things, both are quite harmless:

1. Some laptops will flash the power LED when battery is charging. If this is the case, it should stop when battery is fully charged. This can be presumed if the laptop starts normally while LED flashes. If not, suspect step 2 below:

2. Your laptop is either "asleep" (suspended) or in "hibernation" mode.It does this if left for a long time with no activity/input from you. You must simply "wake the laptop up" now:

Look for a symbol on keyboard for "sleeping" (like a half moon with zzzz) and press that key WITH whatever color coded key matches the symbol color (usually "FN" key). If there is no suchkey, press the space bar and hold it down a few seconds.

Then wait. Can take 60 seconds to "wake up" on slower processors.

If this does not work, press AND hold the POWER button for 10 seconds. Then wait 60 seconds and press power key again, briefly, to start laptop normally.

Pressing and holding the power button 6-10 seconds forces a complete system shutdown.

If this happens often, something may be wrong with APM or ACPI settings/driver. You can go to start menu/settings/control panels/power management and adjust settings (or disable sleep/suspend and hibernation if all else fails to resolve situation)

good luck.
