Sobald der Fehlercode verschwindet, steigt die Anlagenleistung.

Sobald means as soon as. It shows that one thing happens immediately after another.

So in this sentence, the idea is:

• the error code disappears
• then the system output increases right away

Compared with wenn:

• sobald = as soon as, with a sense of immediacy
• wenn = when/whenever, more general and not necessarily immediate

So sobald is a more precise choice here.

Because sobald introduces a subordinate clause.

In German subordinate clauses, the conjugated verb usually goes to the end.

So:

• Sobald der Fehlercode verschwindet = As soon as the error code disappears

Structure:

• Sobald = subordinating conjunction
• der Fehlercode = subject
• verschwindet = finite verb, placed at the end

This is a very common German pattern:

• weil er kommt
• dass sie arbeitet
• wenn es regnet
• sobald der Fehlercode verschwindet

Because the sentence begins with a subordinate clause, and that entire clause takes up the first position in the main clause structure.

German main clauses follow the verb-second rule. The finite verb must come in the second position.

Here the structure is:

• Sobald der Fehlercode verschwindet = position 1
• steigt = position 2
• die Anlagenleistung = the rest

So German puts the verb before the subject in this case.

If you started with the main clause instead, you would get:

• Die Anlagenleistung steigt, sobald der Fehlercode verschwindet.

Now the subject comes first and the verb follows normally.

The comma separates the subordinate clause from the main clause.

In German, when a subordinate clause is attached to a main clause, a comma is generally required.

So:

• Sobald der Fehlercode verschwindet, steigt die Anlagenleistung.

That comma is not optional here.

Both are in the nominative case because each one is the subject of its own clause.

• der Fehlercode = subject of verschwindet
• die Anlagenleistung = subject of steigt

You can test this by asking what is doing the action?

• What disappears? → der Fehlercode
• What increases? → die Anlagenleistung

So both are nominative singular.

Because the nouns have different grammatical genders:

• der Fehlercode = masculine
• die Anlagenleistung = feminine

In the nominative singular, the definite articles are:

• masculine → der
• feminine → die
• neuter → das

So the sentence uses the correct nominative singular article for each noun.

Anlagenleistung is a compound noun, which is extremely common in German.

It is made from:

• Anlage = installation / plant / system / facility
• Leistung = performance / output / power

Together, Anlagenleistung means something like:

• system output
• plant output
• installation performance

The exact English translation depends on the technical context.

German often combines words into one noun where English would use two or more separate words.

This is because of how German compounds are formed.

In many compounds, the first noun may appear with an extra linking element or in a stem form that looks slightly different. Here, Anlagenleistung comes from Anlage + Leistung, but the compound form is Anlagen- + Leistung.

You do not always have to analyze this too deeply as a beginner; the important thing is to learn the compound as a vocabulary item:

• die Anlagenleistung

You will see similar patterns in many German compounds.

Yes, it can.

German often uses the present tense to talk about:

• general truths
• repeated events
• scheduled or expected future events

So this sentence can mean:

• a general technical rule
• something that happens whenever this condition is met
• something that will happen next

German does not need a special future form here. The present tense is completely natural.

Yes, absolutely.

That version is also correct:

• Die Anlagenleistung steigt, sobald der Fehlercode verschwindet.

The meaning stays the same. The main difference is emphasis and sentence flow.

• Starting with Sobald... emphasizes the condition first.
• Starting with Die Anlagenleistung steigt... emphasizes the result first.

Both are normal German.

Steigt comes from steigen, which means to rise or to increase.

It is a good choice when something goes up by itself or is described as increasing in level or value.

Here it suggests that the output/performance rises once the error code disappears.

A different verb, such as erhöht sich, could also be possible in some contexts, but steigt is very natural and concise for technical statements like this.

Because verschwinden is an intransitive verb meaning to disappear.

So:

• der Fehlercode verschwindet = the error code disappears

It is an active verb form, but the meaning is naturally something that happens to the subject itself.

There is no passive construction here. A true passive in German would look different.

It can be understood as either, depending on context, but it most naturally sounds like a general rule or recurring process.

That is because:

• it uses the present tense
• it has a technical, factual style
• sobald often introduces a condition that regularly leads to a result

So it sounds like:

• whenever the error code disappears, the system output rises

If the surrounding context were about one specific situation, it could also refer to a single event.
