Если снова будет такая поломка, я сразу позвоню диспетчеру.

Russian and English work differently here.

In Russian, when an if-clause refers to the future, you normally use the future tense:

• Если будет... , я позвоню...

So Если снова будет такая поломка is completely normal Russian.

In English, future in if clauses is usually avoided, but Russian does not follow that rule. A literal structure like If there will be such a breakdown again sounds odd in English, but in Russian it is standard.

Because поломка is a feminine noun, and такой has to agree with it.

Agreement here is:

• masculine: такой
• feminine: такая
• neuter: такое
• plural: такие

So:

• такая поломка = such a breakdown / this kind of breakdown

The adjective-like word такой changes form to match the noun’s gender, number, and case.

Такая here means something like:

• such a
• this kind of
• the same kind of

So такая поломка suggests a breakdown of this sort, probably one already known from context.

It can sound slightly more specific than just поломка. Compare:

• Если снова будет поломка... = If there is a breakdown again...
• Если снова будет такая поломка... = If there is this kind of breakdown again...

So такая points to the type/nature of the problem.

Because позвонить takes the dative case for the person you call.

The pattern is:

• позвонить кому? = to call whom?

So:

• диспетчер = dispatcher
• диспетчеру = to the dispatcher

Other examples:

• Я позвоню маме.
• Она позвонила врачу.
• Мы позвоним начальнику.

This is different from English, where we simply say call someone without a visible case ending.

Позвоню is the perfective future of позвонить. It means a single completed action: I will make the call.

That fits this sentence well, because the speaker means:

• if this happens, I will immediately place a call

Compare:

• позвоню = I will call once / I will make the call
• буду звонить = I will be calling / I will call repeatedly or over some period

Here, позвоню is the natural choice because the action is a one-time response to the breakdown.

They differ in both tense and aspect.

• звоню = I am calling / I call
  (present tense, imperfective)
• позвоню = I will call
  (future tense, perfective)

Because the sentence talks about a future situation and a future reaction, позвоню is needed.

You could not say:

• Если снова будет такая поломка, я сразу звоню диспетчеру.

That would sound wrong in standard Russian for this meaning.

Yes, Russian often omits subject pronouns when they are clear from the verb form.

So this is also possible:

• Если снова будет такая поломка, сразу позвоню диспетчеру.

That still clearly means I will call, because позвоню already shows first person singular.

Including я can do a few things:

• make the sentence slightly clearer
• add mild emphasis
• make the structure feel more balanced

So я is not required, but it is perfectly natural.

Сразу means immediately / right away, and its position before the verb is very natural.

• я сразу позвоню диспетчеру

This emphasizes the quick response: I’ll call the dispatcher right away.

Russian word order is flexible, so other placements are possible, for example:

• Я позвоню диспетчеру сразу.
• Сразу я позвоню диспетчеру.

But the original version sounds the most neutral and natural in everyday speech.

Yes. Russian word order is much more flexible than English word order.

For example, these are all possible:

• Если снова будет такая поломка, я сразу позвоню диспетчеру.
• Я сразу позвоню диспетчеру, если снова будет такая поломка.
• Если будет снова такая поломка, я сразу позвоню диспетчеру.

However, they are not all equally neutral.

The original version sounds very natural because it presents:

1. the condition first
2. then the result

That is a common and clear structure in Russian.

Yes, опять could be used here.

• снова = again
• опять = again

In many contexts they are interchangeable:

• Если снова будет такая поломка...
• Если опять будет такая поломка...

The difference is mostly stylistic:

• снова can sound a bit more neutral or formal
• опять is very common in everyday speech and can sometimes carry a shade of annoyance, depending on context

So in this sentence, снова sounds slightly more neutral.

Because Если снова будет такая поломка is a subordinate clause introduced by если.

Russian normally separates this kind of clause with a comma:

• Если ..., ...

So:

• Если снова будет такая поломка, я сразу позвоню диспетчеру.

This is standard punctuation.

Not exactly.

• поломка = a breakdown, something has broken
• неисправность = a fault/malfunction, often more technical
• проблема = a problem, very general

So поломка suggests an actual mechanical or technical failure.

Depending on context, Russian speakers might choose different words:

• поломка if something broke
• неисправность if a device/system is malfunctioning
• проблема if speaking more generally

In your sentence, поломка sounds concrete and practical.

Not in its main reading. The sentence most naturally means a future specific condition:

• If this kind of breakdown happens again, I will call the dispatcher immediately.

The two future forms:

• будет
• позвоню

make it sound like a future response to a possible future event.

If you wanted a habitual meaning, Russian would normally use a different structure, often with present tense or wording that clearly shows repeated habit.
