Granules sticks on the cutlery, what to do?

1.       Either the cutlery is still dirty

1.1.    Then clean the cutlery again and then throw it into the machine

Or:

2.       The dishwasher doesn’t work properly, too much rinse aid is used

2.1.    Clean the cutlery by hand. Then swivel under clean water and then throw it into the polishing machine

Granules falls out of the machine, what to do?

This could have the following reasons:

1.       The granule was too wet

1.1.    If the granule is wet, the volume of each corn increases, it pushes up through the holes of the sieve. Because of that it falls out of the machine. The granule can get too wet, if the recommended heating time is not maintained

1.2.    The cutlery was thrown in too wet. Drain the cutlery so that not too much water comes into the machine

1.3.    The machine was already turned off, even though the granule was still wet. Let the machine run for 30 minutes after using, so the granule can dry

Or

2.       There is too much granule in the machine

2.1.    Remove granule

Or

3.       Spoons transport granule out of the machine

3.1.    The axial fan is defective, let it replace by qualified employee. Due to the shape of the spoons, however, this can’t be ruled out completely

 

Granule don’t get warm, is this normal?

If the granule doesn’t heat up, the heating is probably defective -> Let it repair by a qualified electrician

 

What to do if the UVC-lamp won’t turn on?

Then the UVC-lamp is defective -> Change the lamp as described in the operating instruction

 

Can it happen that dust settles on the cutlery?

1.       Either through new granule

1.1.    Fresh granule may cause dust deposits at the beginning. If the granule heats as prescribed, empty 4-5 shot glasses of water into the machine

Or

2.       By rinse aid / dishwashing liquid in the dishwasher

2.1.    The cutlery is greasy and therefore granule remains dust. To check this, clean the cutlery by hand, finally under clear, running water. Throw the cutlery again in the polishing machine. If the problem no longer occurs, it was the type or amount of rinse aid used.

The cutlery doesn’t come out of the machine, what can I do against it and where did it go?

1.       There is not enough granule in the machine

1.1.    If there is too less granule in the machine, the cutlery can’t be transported. Do a granule change. Use only our original Dörr polishing granule

Or

2.       The cutlery has jammed

2.1.    Turn off the machine, open the lid and, if necessary remove the cutlery. If it happens more frequently, the cause may be swollen granule

 

My Cutlery Polishing Machine achieves a much worse polishing quality than before, what to do?

This can be due to the following reasons:

1.       The cutlery was in too dry

Or

2.       A defective heating element

2.1.    Turn off the machine and check the temperature of the granule by hand. The granule must be noticeably warm. If this is not the case, the heating is defective. Call the customer service

Or

3.       The granule is too old

3.1.    The granule should be changed every 4 at least after 8 weeks, depending on the through out or rising quality

The cutlery accumulates in the machine

1.       Either the machine has been overfilled

Or

2.       The granule was too wet and swollen

2.1.    If the granule is too wet once it swells up. The granule thus becomes about 20-30% larger. This means that the entire filling volume is about 20-30% larger. As a result, passages of the cutlery parts are also narrower. To avoid this, it’s urgent to observe the heat-up time and the post-drying phases.
