第二句一眼看去分不清自己修还是请别人修

有没有考虑过have有拥有的意思

have作为实义动词的例子：
Mrs. Brown was much disappointed to see the washing machine that she had went wrong again.
作为使役动词的例子：
Mrs. Brown had the washing machine repaird. But it went wrong again. She was much disappointed.
在过去时基调下一定要强调是别人修的提出先行词以后会造成使役形态和过去完成时形态的同型
你不管是口语还是写出来会把90%的红脖干懵
所以一般不那么写

首先机器本身不能go wrong。go wrong一般是指一件事，不能指具体的物。而且第一句的had repaired部分缺主语。第二句就把went wrong换成stopped working或者类似的就可以了。

had had repaired 是什么鬼

两句都错了 重新写

在完成时中是助动词
