PROBLEM SOLVING

6. Mount new SSR with the 2 Allen bolts. Make sure that the heat transfer sticker is applied to the
back (if you ordered your spare from Kees van der Westen Espressonistic Works B.V., the sticker
is mounted before shipment).
7. Remount the electrical connectors.
8. Replace the cover on the SSR.
9. Turn mains switch
to “2”.
10. Check functioning of machine.
11. Remount left hand side panel.
All other Mirages
The Mirage is equipped with three
SSR’s so you have to determine which SSR is failing first. This is
easily checked as the indicator light of the corresponding spiral will not dim.
Procedure
EITHER:
1. Replace the failing SSR (see above).
OR:
I
f you don’t have a replacement SSR available, you can still use the Mirage but it will operate using 2
of the 3 heating spirals.
2. Disconnect the failing SSR from the mains (connector no.2, the mains supply to the SSR), make
sure that you isolate the disconnected wire properly.
3. Turn mains switch
to “2”.
4. Check functioning of machine.
Note!
When you have disconnected a single SSR, the element indicator light will not function although the
machine is operational.
5. Remount left hand side panel.
Failure characteristics when the SSR load is (semi-) continuously uncoupled
Single-phase, normal power, Mirage Duette
First check if a fuse is blown, if not:
There is no power to the heating element, even when the indicator LED on the SSR is on. The
machine will not warm up. The SSR has to be replaced immediately, see above for procedure.
Note!
Similar characteristics occur when the safety overheating switch has been activated. The difference is
that no mains voltage is measured on connector no.1 when the SSR is failing while voltage is
measured on connector no.1 when the safety overheating switch has been activated.
All other Mirages
Power to the heating element is limited to 2 of the 3 heating spirals. With low to moderate use you
may not even notice that the SSR has failed unless you have observed that the corresponding
indicator light never lights up. Heating up from cold will take a little longer than normal and the
machine may not keep its operational pressure when heavily used.
Use a voltage meter to check if connector no.1 on the SSR gets mains power when the indicator LED
on the SSR is lit. Use a 2-probe voltage meter with one probe on a neutral wire (blue) on the
