I did as you suggest enabling "spellcheck" component in select RH.
<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
</lst>
<arr name="components">
<str>spellcheck</str>
</arr>
</requestHandler>
Response contains error 500
