3. Maintenance Items
Clamp Connections
Check hose clamps for leaks and clamping torque, retighten if needed, replace clamps if
defective. EPDM hose clamps must be replaced if brittle.
Drying System
Dryer system components must be checked for performance and leaks. The entire sys-
tem needs to be thoroughly cleaned periodically. Check air hoses for cracks and other
errors. This switch serves to shut down the heater power (K18) in case of insufficient
blower efficiency.
.
Option pressure differential for blower unit
When reaching a pressure differential of 1.7 k Pa (17 m bar), air filters have arrived at
the end of their usefulness and “filter replace” will be displayed.
Over time, the sealing system
on the heat box is getting
pushed out and need to be
returned to the original posi-
tion.Caution, there is a pres-
sure switch inside the heater
box (P18).
Replace main filter (77317)
after about 500 h of service,
pre-filter (74422) after about
300 h of service.

Technical Manual WD 230 and WD 250
Rev. 1.8 PF Page 10 73018_E rev 1 8-Technical Manual.doc
Assembly of the blower box
Dosing System
Check dosing system for leaks and accuracy. The dosing hoses
should be replaced at each service cycle. Check connection el-
bows of wash chamber for leaks and hose connections for clamp-
ing torque of clamps. At each maintenance cycle or replacement
of a safety related component, system needs to be recalibrated.
Frequency: min. once per year!
The dosage system must be newly calibrated after every mainte-
nance service or every change of detergents!
Flow Meter (Option)
The flow meters must be regularly checked for their proper func-
tion. The number of pulses of water is approximately 4000 beats
per liter.
Water Intake Valves
The water intake valves must be checked for connection safety and throughput capacity.
In case of improper tightness, valves must be replaced. The valve pre-filters must be
cleaned or replaced if damaged.
Recoil Cap at Entry of Water
Due to hygienic reasons, the silicone barrier should be checked regularly at the entry of
water. In case of discoloration, the silicon barrier ought to be changed (Item No 74146).

Technical Manual WD 230 and WD 250
Rev. 1.8 PF Page 11 73018_E rev 1 8-Technical Manual.doc
Wash System
Check wash system for impurities, remove foreign objects and clean. Check and clean
water jets of wash arms and docking ports.
Function check of sleeves and retaining springs of water docking ports.
Make sure that bearing rings of wash arms are in good condition, replace if needed.
Check drain valve and re-circulation pump for proper function and leaks.
Cleaning of Wash Arms
The wash arms must be cleaned and bone rests removed after every maintenance ser-
vice. Possibly, the wash arm bearing must be removed in order to facilitate the proce-
dure and to have better access. The plastic bearing can be opened, as shown below,
counterclockwise to the wash arm.
Check valve
Does the check valve Opens?

Technical Manual WD 230 and WD 250
Rev. 1.8 PF Page 12 73018_E rev 1 8-Technical Manual.doc
Door
Check gear belt of door, adjust by means of door spanner if needed.
Functional check of entire door system.
Use mild detergent to clean door seal, coat with Silicon grease.
Door pressure: check linear motor for proper function.
Periodic maintenance is highly recommended for reasons of operational safety. Profes-
sional disassembly is required (Customer Service Belimed). The collection trough of in-
ner door must be given special attention. Hoses of door drainage must periodically be
replaced.
Electric Installation
Check entire electric installation (burn and melt traces). Replace damaged components.
Make sure that all plug and clamp connections are in good shape, replace suspicious
connections.
Temperature Monitoring System
The sensors and limiters of the temperature monitoring system must be checked for
proper function. Damaged or visibly altered components must be replaced.
Find itemized maintenance. Thus, efficient and comprehensive maintenance service is
assured.
Remove housing and check
seal. Remove orange color
air hose and check for leaks
following several water cy-
l
Check leak water return
hose for brittleness .

4.2.3 Validating mode!
This module is suitable for validating the dosage. In this step the
actual dosing quantity is indicated in ml, which is to be tested while
validating.
Individual steps may be bypassed form the beginning.
By means of ↨door switch, draining action my be stopped, the door
opened to remove a water sample. Again using door key ↨, process
may be resumed.
The programmed dosage, the effectively proportioned amount addi-
tive in ml, the respective medium, target temperature and program
duration for respective step will be displayed.

Programming the programs:
Without Mix Dosing / Doser 1 = 2.6 ml/L

Using Mix Dosing, per phase maximum 4 detergents may be dosed
with appropriate concentration.
If in doing unit D, instead of a number a letter from A – F is entered,
mix doing is activated. To each letter, a maximum of 4 concentra-
tions may be assigned. The software activates a maximum of 2
dosing units simultaneously (otherwise, max. safety is exceeded).
