EcoSmart boiler SERVICE MANUAL Marco Beverage Systems Ltd.
CONTENTS: 1. 2. INTRODUCTION SAFETY INSTRUCTIONS 3 4 3.
1. INTRODUCTION: The information provided in this manual is intended to assist in the installation and maintenance of the Marco EcoSmart Boiler. Please read the instructions carefully to prevent accidents and ensure an efficient installation. This manual is not a substitute for any safety instructions or technical data affixed to the machine or its packaging. All information in this manual is current at the time of publication and is subject to change without notice.
3. BASIC INSTRUCTIONS : 3.1. INSTALLATION DETAILS: Electrical installation: Electrical specification: 2.8kW-230V-50Hz A moulded 13A plug is factory fitted. A suitable 13A outlet is all that is required. Plumbing installation procedure: Mains water pressure required (limits): 5-50psi (35-345kPa) Fit a stop Valve on a cold water line and attach a 3/4" BSP male fitting, (e.g. 3/4" x 1/2" 311 or washing machine type stop valve). Connect straight tailpiece of the hose to the stop valve fitting.
Power Button EcoMode Button Figure 1: Machine User Interface NOTE: Because the boiler is electronically controlled no priming is necessary. The element cannot switch on until a safe level of water is reached. PLEASE REFER TO INSTRUCTION BOOKLET FOR TEMPERATURE CALIBRATION. 3.2. TROUBLESHOOTING The Ready/Status light signals various errors or problems. A cycle of red flashes indicates an error.
3.3. MAINTENANCE: Marco machines have been designed to give many years of trouble free service. Marco Beverage Systems manufacture and test to ISO9002:2000 standard. The only regular maintenance required is occasional de-scaling. Descaling Procedure: Isolate machine from power supply. Isolate machine from water supply. ALLOW TO COOL COMPLETELY! Drain water from machine. Remove all lids. Remove as much scale as possible by hand, paying particular attention to level probes (White plastic with steel tab).

4.3. ACCESS TO INTERNAL COMPONENTS: To access the tank: Allow to cool. Remove the outer lid. Ensure that the tank is cool, before removing inner lid. To remove inner lid, undo 4 butterfly nuts The tank is now accessible for cleaning. To access the internal components: Ball Stud Spring Clip Ball Stud/ Spring Clip locations Service Manual 1000677 EcoSmart PB10 1000678 EcoSmart hiDeck 221110.
Disconnect the machine from the electrical supply. Allow to cool sufficiently. The metal Front Fascia Top and Bottom panels are fixed to the surround with ball studs that lock into spring clips mounted in the surround panel – refer to picture above. To separate the ball studs from the spring clips insert a flat headed screwdriver at the locations indicated on the picture and lever apart the front panels from the surround.

4.6. TROUBLESHOOTING – DI AGNOSTIC GUIDE: NOTE FOR THE ECOSMART RANGE IN ADDITION TO THE STATUS LED FLASHING TO INDICATE AN ERROR – THE DISPLAY WILL ALSO PROVIDE INFORMATION 1 FLASH CYCLE – LOW LEVEL PROBE DISCONNECTED Display pattern: 1 flash then a short pause - repeated. Check and Action Check the wiring to the Low Level probe and the Probe inside the tank. Check probe connection to the lower PCB 2 FLASH CYCLE – BELOW LOW LEVEL Display pattern: 2 flashes then a short pause - repeated.
This is a non recoverable error. The machine needs to be reset when this problem is solved. Probable causes: 1. The elements have failed 2. Wiring fault Action required: 1. Check that the resistance on the elements. If there is a reasonable resistance (15-25Ω)on the element it probably has not failed, so the wiring might be at fault. 5 FLASH CYCLE – THERMISTOR OPEN CIRCUIT Display pattern: 5 flashes then a short pause - repeated.
4.7. Tank Components The tank internals are detailed below. Care should be taken when cleaning inside the tank. The level probes provide much of the control inputs into the PCB and are critical to the operation of the machine. The wiring to these should be checked regularly and the probes themselves should be cleaned whenever the machine is serviced. There are 3 level probes on the machine. Only the low level probe is visible in the picutre.
4.8. Descaling Procedure To descale the machine thouroughly: Unplug the machine. Disconnect from the water supply. Drain as much water from the tank as possible. Remove the lids and allow the machine to cool completely. Drain all the water from the machine. Attempt to remove as much scale as possible by hand. Reconnect machine and start up once again. Add a descale solution (follow instructions as given).
