Bean to Cup

Bean to Cup Coffee Machine Cleaning Schedule

Bean to Cup machines require a little more cleaning than traditional espresso machines. This is because the technology is more complicated and fresh milk is delivered directly through the machine. Milk is a live product as has to be flushed through regularly.

Cleaning schedules detailed below are for guidance only and may vary depending on machine type, quantity of coffee served and the quality of your water supply.

Daily Cleaning Schedule - Milk flush program using the manufacturers recommended milk cleaning brand, such as Puly Milk Cleaner, then repeat with fresh water. This should take approximately 5 minutes.

Weekly Cleaning Schedule - Internal system clean using the manufactured recommended cleaning tablet such as Jura cleaning tablets or Franke cleaning tablets. This should take approximately 25 minutes.

Monthly Cleaning Schedule - System De-scale using the manufacturers recommended de-scaling agent such as Jura de-scaling tablets or Franke de-scaling ready to use liquid. This should take approximately 40 minutes and should be carried out if your machine is plumbed into the water mains with a water filter attached, or water tank model. Most water filters have up to 30% bypass of unfiltered water so lime-scale build up can still build up in your machine.

Annual Servicing - We recommend that an annual service is carried out every 12-15 Months which can be arrange by Denby Dale Coffee Ltd using our service coffee machine engineer partners from Jura UK.

This is a preventative service in which a thorough check of the following are conducted; grinder and brew unit (both have a life cycle of 15-20k drinks, functionality, leaks and damage. Seals, O rings and wear and tear items and  may be replaced if required and are usually covered the the service cost.

If a part covered by the warranty requires a replacement, this will be conducted without charge. This will not however nullify the charge for the service.

Prices vary depending on if you buy your coffee products from us. We substitute charges for our coffee supply customers.

 

Troubleshooting Guide

8 out of 10 bean to cup issue calls we receive are quite simple and can quickly be resolved in a matter of minutes. Here are the most common

Milk not frothing properly
You will have a milk blockage either in the tubes or attachments or the machine requires a descale. Check and clean all thoroughly. Make sure you are using the correct cleaning brush and have a paperclip to force a milk blockage from the air valve. See visual below.

Milk not being dispensed
As above

Drip tray missing message
The metal sensor connections at the back of the drip tray are not connecting with the machine. Try removing and replacing the tray a couple of times. Failing that, the small metal sensors may need a wipe or replacing. These simply unclip from the rear of the tray.

Beverage not hot enough
First of all, drinks from bean to cup machines are not kettle hot. As a nation of instant coffee drinkers, we like to almost burn our mouth when we drink our coffee at home. Bean to cup machines dispenses real Italian style coffee. Coffee is dispensed at just under 90 degrees and milk at nearer 70 degrees, so for example a cappuccino will be mainly milk. The drinks however should be hot enough to enjoy. Settings can be changed using the program mode to increase the temperatures:

  • Set the temperature setting to high

  • Increase the volume of water in your milk based drinks

Alternatively, the temperature of drinks can decrease if the machine requires a de-scale so ensure your equipment is cleaned and descaled at the correct frequencies. It is also important to have your coffee machine serviced regularly. Ask us for details.

Bean to Cup error codes for the Jura Impressa & Franke coffee machine

Error 1 - Defect in the steam heating unit

Causes / troubleshooting:
Thermal sensor defective – replace thermal sensor
Cable to the thermal sensor is broken or contact pins are corroded – replace / repair cable
Heating or thermal cut-out are defective – measure and replace parts if required
Triac on the power board is defective. The heater heats up until triggering the overtemperature protection - replace the overtemperature protection (thermal cut-out) and the power board or a single triac.

Error 2 - The machine is too cold

Causes / troubleshooting:
Thermal sensor defective – replace thermal sensor
Room temperature is too low (<15°C) – store the device for several hours at room temperature (20°C). (This proceeding is only necessary if the device was really located in a too cold surrounding)

Error 3 - Sensor problem / fault in the heating circuit

Causes / troubleshooting:
Thermal sensor defective. (Determine resistance value; at 20°C approx. 12kOhm) – if this value differs clearly, the thermal sensor needs to be replaced.
Cable to the thermal sensor is broken or contact pins are corroded – replace/repair cable.
Control board defective – replace electronics / replace EPROM.
Heating or thermal cut-out defective – measure and replace parts if necessary.

Error 4 - Temperature measuring fault of steam circuit

Causes / troubleshooting:
Thermal sensor defective. (Determine resistance value. at 20°C approx. 12kOhm) – replace thermal sensor
Cable to the thermal sensor is broken or contact pins are corroded – replace/repair cable.
Control board defective – replace electronics / replace EEPROM.


Failure 5 - Required temperature not reached

Causes / troubleshooting:
Thermoblock has blown. (resistance value cannot be defined/is infinite) – replace thermoblock.
Thermal cut-out (overtemperture protection) is blown – replace thermal cut-out. (It is recommendable to replace the temperature sensor as well to avoid another fault)
Power electronic is defective (resistance value between the connections cannot be determined, there is no voltage on the connector pins) - replace triacs of the power board or entire power board.
Attention! Determine resistance value of the thermoblock to avoid subsequent errors.

Error 6 - Electronic scaling monitor reports an error

Causes / troubleshooting:
On the rear, some machines have a reactive cable. A contact pin which contains a resistor coated by a protective tube.
This sensor is used for measuring the scaling degree, which, however, has never been completed.
Failure 6 actually means: The sensor is above the measuring tolerance –clean the contact pins, dry them and apply contact spray if necessary.

Error 8 (Most common error message among all Jura machines)

Problems with positioning the brewing unit.

Causes / troubleshooting:
Brewing unit difficult to move due to worn, swollen or broken sealing rings
- replace sealing rings or the entire brewing unit.
Encoder defective. (count error at the head of the brewing unit or at the drive pinion of the gear motor) A wrong position of the brewing unit is transmitted to the electronics. - check encoder cable or replace encoder if necessary
Brewing unit motor does not move (machine is clicking instead), transformer is defective. - replace transformer.
Motor or motor mounting defective. (Chattering or very low buzzing) – replace brew group motor.
Extremely loud chattering of the brew group during routine operations (up and down movement of the brew group after switch-on): After replacing the sealing rings or the entire brew group, some screws have been omitted. The drive unit jumps over the drive pinion and chatters.

 Error 15 (Vent Flaps not closing due to suspect coffee bean) - Don't overfill the bean hopper, open close hopper flap, clean down top then restart.

Message: Tap is closed.

Close steam/water switch.

Causes / troubleshooting:
Defect of the steam board – replace steam board or reed contact on the steam board.
Cable to the control board is corroded or there is a cold junction of a soldering connection. - resolder the soldering points on the steam board, check contacts on the control board. (contact spray does not help in this case)
Coffee grounds are too wet/sludgy – coffee powder and water in the coffee grounds container, no coffee at the spout.
See failure 8

Message: Service (only for older machines) No clear failure classification

Causes:
Temperature sensor of the coffee unit is defective.
Temperature sensor of the steam unit is defective (only if the tap is opened).
Control board defective
Encoder defective
Flowmeter defective
Drainage valve defective
Power board defective

Message: Fill system

Error in the fluid system (water circuit)
Causes / troubleshooting:
Leaks in the fluid system. - localise the leaks and seal them.
Blockage in the fluid system, no water can be fed. - localise blockage and replace blocked components (valves/heater/tubes) if necessary.
Flow meter – count error - open the flow meter by a quarter turn and clean it, replace it if necessary.

• Message: Fill beans / coffee outlet stops prematurely.

Causes / troubleshooting:

Grinder worn down - replace grinding stones or clean them with Grindz grinder cleaner if necessary.
Dirt in the grinder - dismantle the grinder and clean it. (with Grindz also possible without dismantling)
Wrong type of coffee (glazed coffee beans) – use coarser preground coffee, put the grinder on coarser setting.

'Please Wait' massage - This is probably the mount wire on the thermo unit needs replacing. Engineer required.
