“SHAKEDOWN OPERATION OF NEW ENGINE UNIT
ASSEMBLY”.
NOTE: NOTE: When the new engine unit is installed, the thermistor
(engine) and engine packing B should be reinstalled.
[13] SHAKEDOWN OPERATION OF NEW ENGINE UNIT ASSEMBLY
After the new engine unit assembly is installed, carry out the following
three procedures to avoid the error operation.
1. Remove the two (2) screws holding the back plate cover and
remove the back plate cover. This is to cool the engine unit.
2. Fill the water tank with water and carry out the 1st. stage of “DES-
CALE” function, referring to “Descale Function” on page 5-4. (citric
acid or lemon juice is not necessary.)
3. Then, carry out Drain water function (refer to “Drain Water Func-
tion” on page 5-4).
4. At last, fill the water tank with water and carry out Steam high cook-
ing again for about ten (10) minutes. And check that the error does
not appear on the display.
5. If the error is appeared and the oven stops at above step 4, carry
out step 2, step 3 and step 4.
6. After shakedown operation, reinstall the back plate cover with the
two (2) screws.
REASON
Inside walls of the engine unit assembly have been painted to protect
the engine unit assembly with special paint. And special paint will shed
water initially. By carrying out Steam cooking, paint can be accus-
tomed to water. If this operation is not carried out, the oven will judge
that there is no water in the tank assembly.
And the display will show the error and then the oven will stop.
Because this oven judges that there is water or not by checking on/off
time ratio of the engine unit assembly.
If paint is not accustomed to water, off time will become longer than on
time. At this time, the oven will judge no water.
[14] THERMISTOR (ENGINE) REMOVAL
1. CARRY OUT 3D CHECKS.
2. Remove the engine unit, referring to “ENGIEN UNIT REMOVAL”.
3. Remove the bottom plate, referring to “BOTTOM PLATE
REMOVAL”.
4. Disconnect the connector of the thermistor (engine) from the con-
nector of the main wire harness.
5. Now, the thermistor (engine) is free.
